Today we're announcing Meilisearch v1.10. In this article, we’ll review the most impactful changes. For an exhaustive listing, check out the [changelog](https://github.com/meilisearch/meilisearch/releases/tag/v1.10.0) on GitHub.

<Callout>
  Meilisearch 1.10 is available on [Meilisearch Cloud](https://cloud.meilisearch.com/?utm_campaign=release-v1-10&utm_source=blog), too—upgrade now!

New: federated search
---------------------

We’re excited to announce that [federated search](__GHOST_URL__/what-is-federated-search/?utm_campaign=release-v1-10&utm_source=blog) is finally coming to Meilisearch. This feature extends the [multi-search API](https://www.meilisearch.com/docs/reference/api/multi_search?utm_campaign=release-v1-10&utm_source=blog#perform-a-multi-search) to allow you to merge results from multiple queries into a single, unified response. You can now search different indexes and get the most relevant results across the entire dataset, not only the most relevant for each index.

For SaaS platforms that need to search across various types of resources or ecommerce sites with diverse product categories, federated search is a game-changer.

Here is an example payload for making a [federated search request](https://www.meilisearch.com/docs/reference/api/multi_search?utm_campaign=release-v1-10&utm_source=blog#federated-multi-search) against the `movies` and `comics` indexes:

```json
{
  "federation": {
    "offset": 5,
    "limit": 10
  },
  "queries": [
    {
      "q": "Batman",
      "indexUid": "movies"
    },
    {
      "q": "Batman",
      "indexUid": "comics"
    }
  ]
}
```

In this example, the [federated search response](https://www.meilisearch.com/docs/reference/api/multi_search?utm_campaign=release-v1-10&utm_source=blog#response-200-ok-1) will look like this:

```json
{
  "hits": [
    {
      "id": 42,
      "title": "Batman returns",
      "overview": "..",
      "_federation": {
        "indexUid": "movies",
        "queriesPosition": 0
      }
    },
    {
      "comicsId": "batman-killing-joke",
      "description": "..",
      "title": "Batman: the killing joke",
      "_federation": {
        "indexUid": "comics",
        "queriesPosition": 1
      }
    },
 ],
  "processingTimeMs": 0,
  "limit": 2,
  "offset": 0,
  "estimatedTotalHits": 2,
  "semanticHitCount": 0
}
```

### Query weighting

Federated search isn't just about combining results; it's about making those results more meaningful and relevant. Thanks to [query weighting](https://www.meilisearch.com/docs/reference/api/multi_search?utm_campaign=release-v1-10&utm_source=blog#federationoptions), you can prioritize certain queries over others, ensuring that the most important data rises to the top.

The example payload below uses **query weighting** in a federated search to give more importance to documents where the `boosted` field is `true`:

```json
{
  "federation": {},
  "queries": [
    {
      "q": "iphone case",
      "indexUid": "products",
      "filter": "BOOSTED = true",
      "federationOptions": {
        "weight": 3.0
      }
    },
    {
      "q": "iphone case",
      "indexUid": "products"
      // federationOptions.weight defaults to 1
    }
  ]
}
```

New: language settings for queries and documents
------------------------------------------------

By default, Meilisearch automatically detects the language used in documents and queries. This comes with some limitations for edge cases. Meilisearch 1.10 introduces new language settings that allow users to manually customize their language preferences.

There are two ways to state the language used in a search:

*   Set the language used in a query
*   Set the language used in a document field

### Setting the search query locale

You can define which language is used in a query in the [search parameters](https://www.meilisearch.com/docs/reference/api/search?utm_campaign=release-v1-10&utm_source=blog#query-locales).

**Example payload for searching with query `locales`:**

```json
{
   "q": "進撃の巨人",
   "locales": ["jpn"]
}
```

### Setting the document attributes’ locales

You can define which language is used in your dataset via the [index settings](https://www.meilisearch.com/docs/reference/api/settings?utm_campaign=release-v1-10&utm_source=blog#localized-attributes).

**Example payload for settings with `localizedAttributes`:**

```json
{
  "localizedAttributes": [
    {
      "locales": ["jpn"], 
      "attributePatterns": ["*_japanese"]
    }
  ]
}
```
<Callout>
  Meilisearch support all [ISO-639-2B](https://en.wikipedia.org/wiki/List_of_ISO_639-2_codes) locales.
</Callout>

Self-hosting: Ubuntu v20 is now required
----------------------------------------

If you’re self-hosting Meilisearch, take note: Meilisearch 1.10 now requires **Ubuntu version 20**. This update ensures compatibility with the latest features and maintains optimal performance and security. We advise reading the documentation on [how to upgrade your Ubuntu release](https://documentation.ubuntu.com/server/how-to/software/upgrade-your-release/).

<Callout>
  This change does not affect [Meilisearch Cloud](https://meilisearch.com/cloud?utm_campaign=release-v1-10&utm_source=blog) users.
</Callout>

Experimental: AI-powered search DX improvements
-----------------------------------------------

### New: custom headers to REST API-based embedders

Meilisearch 1.10 supports sending custom headers to your API-based embedding service. When using the `rest` source for your [embedder settings](https://www.meilisearch.com/docs/reference/api/settings?utm_campaign=release-v1-10&utm_source=blog#embedders-experimental), Meilisearch now accepts an optional `headers` object. These headers will be added to all requests made to the embedder API.

**Example payload for embedder settings:**

```json
{
  "source": "rest",
  "apiKey": "•••••••••••••••••",
  "headers": {
    "Custom-Header": "value"
  }
}
```

### New: quality of life improvements

Additionally, we added some minor changes to make working with Meilisearch AI-powered search API easier:

*   Embedder settings now accept a `url` parameter for OpenAI embedder to access OpenAI through a proxy
*   Embedder settings now accept a `dimensions` parameter for ollama embedder
*   Meilisearch now includes `_vectors` in the response for documents without vectors (only when `retrieveVectors` is enabled)

### ⚠️ Breaking: REST API-based embedders breaking changes

The API for [configuring an embedder based on a REST API](https://www.meilisearch.com/docs/learn/experimental/vector_search?utm_campaign=release-v1-10&utm_source=blog#generate-vector-embeddings) (e.g., OpenAI, Mistral, etc.) has quickly evolved and to avoid confusion, we have decided to reorganize the parameters in dedicated `request` and `response` fields.

In practice, this change:

*   removes `query` , `inputField`, `inputType`, `pathToEmbeddings` and `embeddingObject` fields
*   adds `request` and `response` fields

Take a look at the example below to learn how to migrate to the new syntax.

**Before** — With Meilisearch 1.9

```json
{
   "source": "rest",
   "url": "https://localhost:10006",
   "query": {
     "model": "minillm",
   },
   "inputField": ["prompt"],
   "inputType": "text",
   "embeddingObject": ["embedding"]
}
```

**After** — Starting with Meilisearch 1.10

```json
{
   "source": "rest",
   "url": "https://localhost:10006",
   "request": {
     "model": "minillm",
     "prompt": "{{text}}"
   },
   "response": {
     "embedding": "{{embedding}}"
   }
}
```

#### Upgrade procedure

This procedure is only necessary if you're using REST API-based embedder. To upgrade to Meilisearch 1.10, follow these steps:

1.  Remove embedders with source `"rest"`
2.  Update your [Meilisearch Cloud project](https://www.meilisearch.com/docs/learn/update_and_migration/updating?utm_campaign=release-v1-10&utm_source=blog#updating-meilisearch-cloud) or [self-hosted Meilisearch instance](https://www.meilisearch.com/docs/learn/update_and_migration/updating?utm_campaign=release-v1-10&utm_source=blog#updating-a-self-hosted-meilisearch-instance) as usual

Experimental: `CONTAINS` filter operator
----------------------------------------

Meilisearch 1.10 introduces the `CONTAINS` operator. This is still in the experimental stage due to some performance issues we’re working to resolve. This new [filter operator](https://www.meilisearch.com/docs/learn/filtering_and_sorting/filter_expression_reference?utm_campaign=release-v1-10&utm_source=blog#contains) allows to check if a substring is included in a larger string.

Given the document `{ id: 1, name: "Keffir" }`, you can use the filter as follows:

*   `name CONTAINS kef` — search will match the document
*   `name CONTAINS clifford` — search will not match the document

<Callout>
  Remember all filters used lowercase, normalized strings (all accents are removed).

</Callout>

Experimental: update documents with a function
----------------------------------------------

Meilisearch 1.10 allows you to edit documents by executing [a Rhai function](https://rhai.rs/). This allows you to update only a part of your dataset using filters. Additionally, using a function allows you to implement dynamic logic based on your documents’ data.

The following payload updates the title of all documents with `id` above 3000:

```json
{
  "filter": "id > 3000",
  "function": "doc.title = `✨ ${doc.title.to_upper()} ✨`"
}
```

This also enables more complex use cases, like [implementing a decaying ranking strategy](https://felx.me/2021/08/29/improving-the-hacker-news-ranking-algorithm.html). Depending on your needs, you might implement a function such as the following that will be run regularly by a Cron job.

```json
{
  "context": { "now": 1715423249 },
  "function": "
    // `posted_at` and `now` are Unix Epoch timestamps in seconds
    // they must be converted to hours.
    let age_hours = (context.now - doc.posted_at) / 60 / 60;
    doc.ranking_score = doc.upvotes ** 0.8 / (age_hours + 2) ** 1.8;
  "
}
```

Meilisearch 1.10

We're excited to unveil Meilisearch v1.9. In this article, we’ll review the most impactful changes. For an exhaustive listing, check out the [changelog](https://github.com/meilisearch/meilisearch/releases/tag/v1.9.0) on GitHub.

<Callout>
  Meilisearch 1.9 is available on [Meilisearch](https://cloud.meilisearch.com/?utm_campaign=release-v1-9&utm_source=blog) Cloud, too—upgrade now!
</Callout>

New: ranking score threshold
----------------------------

Meilisearch 1.9 allows excluding search results with low ranking scores. When using the new `rankingScoreThreshold` option, Meilisearch will not return any documents below the defined threshold.

```bash
curl \
 -X POST 'http://localhost:7700/indexes/movies/search' \
 -H 'Content-Type: application/json' \
 --data-binary '{
    "q": "green ogre living in a swamp",
    "hybrid": { 
	    "semanticRatio": 0.9, 
	    "embedder": "default" 
	},
    "showRankingScore": true,
    "limit": 5,
    "rankingScoreThreshold": 0.2
 }'
```

Using the ranking score threshold when implementing [hybrid search](https://www.meilisearch.com/docs/reference/api/search?utm_campaign=release-v1-9&utm_source=blog#hybrid-search-experimental) removes irrelevant results and allows your [search analytics](https://www.meilisearch.com/docs/learn/analytics/analytics?utm_campaign=release-v1-9&utm_source=blog) to collect the _No search results_ metric properly.

<Callout>
  Excluded results do not count towards `estimatedTotalHits`, `totalHits`, or facet distribution.
</Callout>

New: distinct attribute at search time (group by)
-------------------------------------------------

Meilisearch 1.9 adds the ability to define a [distinct attribute](https://www.meilisearch.com/docs/learn/configuration/distinct?utm_campaign=release-v1-9&utm_source=blog) at search time. Meilisearch will only return one document with the specified attribute value when using the new `distinct` search parameter.

This feature is commonly used in ecommerce applications. Consider a `products` index containing multiple variants of the same product, e.g. `Blue iPhone 15` and `Red iPhone 15` documents that share the same `product_id`. The API call below will return _a single_ iPhone 15:

```bash
curl \
 -X POST 'http://localhost:7700/indexes/products/search' \
 -H 'Content-Type: application/json' \
 --data-binary '{
    "q": "iphone",
    "distinct": "product_id"
 }'
```
<Callout>
  When `distinct` is provided, Meilisearch ignores the index’s [distinct attribute](https://www.meilisearch.com/docs/learn/configuration/distinct?utm_campaign=release-v1-9&utm_source=blog).
</Callout>

New: `frequency` matching strategy
----------------------------------

Meilisearch 1.9 introduces a new [matching strategy](https://www.meilisearch.com/docs/reference/api/search?utm_campaign=release-v1-9&utm_source=blog#matching-strategy) to prioritize results that contain occurrences of the least frequent query terms. When using the `frequency` matching strategy, Meilisearch will deprioritize very common words.

Let’s take the example of the `"the little prince"` query. In our indexed documents, the words `"the"` and `"little"` likely have a lot of occurrences. Consequently, the matching strategy will prioritize documents containing `"prince"` instead.

Experimental: new similar documents API
---------------------------------------

Meilisearch 1.9 introduces a new [AI-powered search](https://www.meilisearch.com/docs/learn/ai-powered-search/getting_started_with_ai_search?utm_campaign=release-v1-9&utm_source=blog) feature that allows searching for documents similar to an existing document.

The following API call searches for documents similar to the document whose [primary key](https://www.meilisearch.com/docs/learn/core_concepts/primary_key?utm_campaign=release-v1-9&utm_source=blog) is `23` in the movies index:

```bash
curl \
  -X POST /indexes/movies/similar
  -H 'Content-Type: application/json' \
  --data-binary '{
    "id": "23",
    "embedder": "default",
  }'
```

Check out the [similar documents API](https://www.meilisearch.com/docs/reference/api/similar?utm_campaign=release-v1-9&utm_source=blog) for more information about additional parameters.

Experimental: avoid re-generating embeddings
--------------------------------------------

When importing a [dump](https://www.meilisearch.com/docs/learn/advanced/dumps?utm_campaign=release-v1-9&utm_source=blog) created with Meilisearch 1.9 or higher, Meilisearch will not re-generate the embeddings. This will avoid unnecessary computing when upgrading your Meilisearch database.

### New: `regenerate` parameter

Additionally, Meilisearch 1.9 introduces a new API to give more fine-grained control over [document embedding generation](https://www.meilisearch.com/docs/learn/ai-powered-search/getting_started_with_ai_search?utm_campaign=release-v1-9&utm_source=blog#generate-vector-embeddings-with-openai). Specifically, it enables embedding generation whenever a document is updated.

The document `_vectors` object now accepts objects in addition to arrays. The provided object accepts a `regenerate` boolean and an optional `embeddings` array.

Consider the example document below with user-provided embeddings:

```json
{
	"id": 42,
	"_vectors": {
		// Embeddings for the `default` embedder
		// Equivalent to `regenerate: true`
		"default": [0.1, 0.2 ],
		// Embeddings for the `text` embedder
		"text": {
			"embeddings": [[0.1, 0.2, 0.3], [0.4, 0.5, 0.6]],
			// Never regenerate embeddings
			"regenerate": false
		},
		"translation": {
			"embeddings": [0.1, 0.2, 0.3, 0.4],
			// Regenerate embeddings when document is updated
			"regenerate": true
		}
	}
}

```

While, in general, you might want to re-generate your embeddings whenever the document is updated, this facilitates migrating from user-provided embeddings to letting Meilisearch handle embedding without incurring unnecessary costs.

Experimental: hybrid search breaking changes
--------------------------------------------

As we move toward [stabilizing AI-powered search features](https://github.com/meilisearch/meilisearch/issues/4733), we introduced minor breaking changes to make the APIs less error-prone.

### Breaking: empty `embeddings` array

Following user feedback that the previous behavior was unexpected and unhelpful, providing an empty `embeddings` array will now tell Meilisearch that the document has no embeddings.

<Callout>
  Before Meilisearch 1.9, an empty `embeddings` array was interpreted as a single embedding of dimension 0.
</Callout>

### Breaking: removed `_vectors` in search results

Starting with Meilisearch 1.9, API responses to [vector search and hybrid search](https://www.meilisearch.com/docs/learn/ai-powered-search/getting_started_with_ai_search?utm_campaign=release-v1-9&utm_source=blog) requests will not include `_vectors` in the response.

However, you can now use the new `retrieveVectors` search parameter if you want API responses to include them:

```bash
curl \
  -X POST 'http://localhost:7700/indexes/movies/search' \
  -H 'Content-Type: application/json' \
  --data-binary '{
    "q": "star wars",
    "retrieveVectors": true
  }'
```

### Breaking: optimizing user-provided `embeddings`

Starting with Meilisearch 1.9, vector embeddings will no longer be stored as-is. Numbers will be cast to floats in canonicalized representation to save storage and optimize performance. Simply put, the vector `[3]` might be stored as `[3.0]`.

Meilisearch 1.9

On June 11, 2024, Meilisearch hosted a live event packed with product updates, sneak peeks, and roadmap discussions. If you couldn't make it, here's a quick recap of what went down.

**AI-powered search refresher and new embedders**
-------------------------------------------------

Our product team took the stage to share insights into developing our AI-powered search solution and outlined our vision for providing ready-to-use components for seamless AI-powered search integration. By adding semantic and AI capabilities to Meilisearch's core keyword and full-text product, we introduced a [hybrid search solution](https://www.meilisearch.com/solutions/hybrid-search) in early 2024.

To streamline the developer experience, we have since added [Ollama and REST embedders](__GHOST_URL__/meilisearch-1-8/) for easier integration within the v1.8 scope.

![](https://lh7-us.googleusercontent.com/docsz/AD_4nXd_QlnM1707ZYLjpOrhzxjZrWDxgdVo3TL5Dewz6dM1ZIbhZp4CcPUJdtDhV4xAA_ZZACDSv8h9JF_d2AoFSNGYNlShW_JOI_s1TrqbEtntN-7pvxW8UnTTdVMNml9oBroLhZfrVprM5dQmM0HiTP55MZPw?key=pr3OBspkNUkqXQYoKJ84OA)

You are welcome to try out the hybrid search feature using our [movie demo database](https://where2watch.meilisearch.com/). 

**New relevancy improvements and smarter search**
-------------------------------------------------

We also introduced several new features designed to _improve search relevancy_ in v1.9:

*   **Negative keyword search**: exclude unwanted results easily.
*   **New frequency matching strategy**: enhance search accuracy by removing the most common term found in the dataset.
*   **Filter by score**: set a baseline _rankingScore_ to return only results considered "good enough" in terms of relevancy.
*   **Get similar documents:** utilize AI to find similar documents within your dataset.

This new feature set is slated for launch on July 1st.

**Query suggestions sneak peek**
--------------------------------

Attendees also got a sneak peek into an upcoming release. The new _query suggestions_ feature aims to enhance search efficiency by returning real-time, relevant suggestions as users type, ordered by popularity. This feature leverages [cloud search analytics](__GHOST_URL__/search-analytics-release/) to generate and rank suggestions based on popularity and relevance. Designed for seamless integration, it requires no new endpoints or tools and is expected to be released in Q3. Ongoing improvements will be based on user feedback.

New: negative search
--------------------

Meilisearch 1.8 allows you to exclude specific terms from your search results using the `-` operator. 

For example, to find documents that contain the word "room" but not "escape", place a `-` before "escape”:

```Bash
curl \
  -X POST 'https://edge.meilisearch.com/indexes/places/search' \
  -H 'Content-Type: application/json' \
  --data-binary '{ "q": "-escape room" }'

### New Ollama embedder

Meilisearch 1.8 introduces support for Ollama models. [Configure the embedder](https://www.meilisearch.com/docs/learn/experimental/vector_search?utm_campaign=release-v1-8&utm_source=blog#generate-vector-embeddings) in your index settings:

```JSON
"default": {
  "source": "ollama", // 👈 Use the ollama source
  "url": "http://localhost:11434/api/embeddings",
  // ☝️ optional, fetched from MEILI_OLLAMA_URL environment variable if missing
  "apiKey": "<your-api-key>",
  // ☝️ optional
  "model": "nomic-embed-text",
  "documentTemplate": "{{doc.field_name}}" // like for openAI and huggingFace sources
}

```

### New REST Embedder

Starting with Meilisearch 1.8, you can use any embedder accessible via a REST API. Here’s how to configure an OpenAI embedder with the `rest` source:

```JSON
{
  "source": "rest",
  "apiKey": "<your-openai-api-key>",
  "dimensions": 1536,
  "url": "https://api.openai.com/v1/embeddings",
  "query": {
    "model": "text-embedding-ada-002"
  },
  "inputField": ["input"],
  "inputType": "textArray",
  "pathToEmbeddings": ["data"],
  "embeddingObject": ["embedding"]
}

```

For more details on the API and available parameters, please consult the documentation on [REST embedders](https://www.meilisearch.com/docs/learn/experimental/vector_search#generate-auto-embeddings?utm_campaign=release-v1-8&utm_source=blog).

### New embedder setting: distribution shift

<Callout>
  This is an advanced API for custom models. OpenAI and Hugging Face models don't require this setting.
</Callout>

Depending on the embedding model, [vector embeddings](__GHOST_URL__/what-are-vector-embeddings/?utm_campaign=release-v1-8&utm_source=blog) are not always uniformly distributed within the [vector space](__GHOST_URL__/what-are-vector-embeddings/?utm_campaign=release-v1-8&utm_source=blog). When vectors are overly clustered, semantic search scores can be very closely ranked. As a result of semantic scores being packed, hybrid results might have sub-optimal relevancy.

To address this issue, you can now shift the distribution of results with an affine transformation. This transformation normalizes semantic scores to prevent them from clustering too high or too tightly, making them more comparable to the [keyword scores](https://www.meilisearch.com/docs/reference/api/search#ranking-score).

```JSON
"default": {
  "source": "huggingFace",
  "model": "MODEL_NAME",
  "distribution": {  // describes the natural distribution of results
    "mean": 0.7, // mean value
    "sigma": 0.3 // standard deviation
  }
}

```

*   The **mean** value represents the central point around which you observe semantic search scores to be densely packed. In the provided code sample, the setting indicates that semantic scores from this model tend to cluster around a mean of 0.7.
*   The **sigma** value determines the spread of ranking scores from the mean (standard deviation). The sigma provided in the code sample above means that before shifting the distribution, the results tend to have an average distance of 0.3 to the mean.

This allows for a more effective comparison of `_rankingScore` between semantic and keyword search results, leading to improved results ranking.

### Breaking: trimmed API response

To speed up the search response and reduce bandwidth usage, Meilisearch v1.8 no longer returns the following fields in the search responses:

*   the `vector` field, which returned the query vector 
*   the `value` field included in the [`vectorSort`](https://www.meilisearch.com/docs/reference/api/search?utm_campaign=release-v1-8&utm_source=blog#vectorsorttarget_vector) object, which is returned when you add \`”showRankingScoreDetails”: true”\` to a search query
*   the `_semanticScore` field; its value is the same as `_rankingScore`, which you should use instead. Set [`”showRankingScore”: true”`](https://www.meilisearch.com/docs/reference/api/search?utm_source=blog&utm_campaign=release-v1-8#ranking-score) in the search parameters

Search robustness improvements
------------------------------

### New search cut-off setting

To enhance stability and performance, Meilisearch automatically terminates any search request that exceeds 1500 milliseconds. 

To adjust this timeout threshold, you can customize the `searchCutoffMs` setting:

```bash
curl \
  -X PATCH 'https://edge.meilisearch.com/indexes/movies/settings' \
  -H 'Content-Type: application/json' \
  --data-binary '{
    "searchCutoffMs": 150
  }'

```

### Experimental: concurrent search requests limit

This release introduces a limit on concurrent search requests to prevent Meilisearch from using excessive amounts of RAM and crashing. The default queue limit is set to 1000 requests. 

To modify this limit, restart your self-hosted instance with the `--experimental-search-queue-size` option:

```bash
./meilisearch --experimental-search-queue-size 100
```

👉 This limit does not impact the search performance. It only controls the number of search requests that can be queued simultaneously to enhance system security.

Meilisearch 1.8

We're excited to unveil Meilisearch v1.7. In this article, we’ll review the most impactful changes. For an exhaustive listing, check out the [changelog](https://github.com/meilisearch/meilisearch/releases/tag/v1.7.0) on Github.

<Callout>
  Meilisearch 1.7 is available on [Meilisearch Cloud](https://cloud.meilisearch.com/?utm_campaign=release-v1-7&utm_source=blog) too—upgrade now!
</Callout>

Improved hybrid & vector search
-------------------------------

<Callout>
  AI search is an experimental feature, read the docs to [enable AI search](https://www.meilisearch.com/docs/learn/experimental/vector_search?utm_campaign=release-v1-7&utm_source=blog#activate-vector-search).
</Callout>

### New OpenAI embedding models

Starting with Meilisearch 1.7, you can use OpenAI’s third-generation embedding models:

*   `text-embedding-3-small`
*   `text-embedding-3-large`

Compared to the previous `text-embedding-ada-002` model, these new models offer improvements allowing to balance search results relevancy and cost efficiency.

The `small` model is more cost-effective, generating smaller vector embeddings that require less storage. The `large` focuses on delivering higher precision in search results, making it ideal to optimize relevancy.

### Configuring OpenAI model dimensions

When using the new `text-embedding-3-small` and `text-embedding-3-large` OpenAI models, you can now configure **dimensions** for your model. When not provided, the model's defaults dimensions are used.

You can do so when updating your settings:

```json
{
  // other settings...

  "embedders": {
    "small": {
      "source": "openAi",
      "model": "text-embedding-3-large",
      "dimensions": 512 // must be >0, must be <= 3072 for "text-embedding-3-large"
    },
  }
}

```

Higher dimensions typically offer more complex embeddings which can lead to more accurate search results. However, increased dimensions are more costly to compute and require more storage.

<Callout>
  You cannot customize dimensions when using OpenAI `text-embedding-ada-002`.
</Callout>

Display ranking scores details at search
----------------------------------------

Meilisearch 1.7 stabilizes the `showRankingScoreDetails` search parameter that was introduced in [Meilisearch 1.3](__GHOST_URL__/v1-3-release/?utm_campaign=release-v1-7&utm_source=blog). This parameter adds a `_rankingScoreDetails` field to each document in search results, enabling further inspection of the search results.

You can include the parameter when making searches:

```sh
curl \
  -X POST 'https://edge.meilisearch.com/indexes/movies/search' \
  -H 'Content-Type: application/json' \
  --data-binary '{
    "q": "batman",
    "showRankingScoreDetails": true
  }'

```

AI's influence on search
------------------------

The rapid advancement of AI technology is undeniably reshaping human-machine interactions. Historically, communication with machines necessitated intermediaries like programming languages and structured scripts.

Now, with the arrival of GPTs and AI-assisted bots, machine-learning models are approaching a deeper comprehension of natural human language. This evolution brings humans and machines closer, changing the way we seek and find information.

From keyword-based searches to discovery-driven inquiries, people’s approach to search evolves: we are moving from searching for known items to exploring unknown territories, searching and finding the concepts instead of focusing solely on words.

Take a streaming media company: the searches across their platform might include the inquiry for a specific movie title, such as "Back to the Future," as well as conceptually-driven searches like "Give me recommendations for a feel-good sci-fi movie from the 80s".

Consider everyday scenarios: spotting an item on the street and using an image to search for it, or conducting voice searches instead of typing in words on keyboards. These are manifestations of our changing search behaviors.

The pinnacle: hybrid search
---------------------------

While traditional search methods excel in keyword-based queries, they falter with complex, nuanced requests. This is where Meilisearch’s new hybrid search approach comes into play, enriching the efficiency and precision of our robust full-text search engine with a depth of semantic understanding, catering to a wide array of use cases driven by customer-generated data.

Integrating models from AI giants like [OpenAI](https://www.meilisearch.com/docs/learn/experimental/vector_search#generate-auto-embeddings-with-openai) (open-source embedders generation feature is set for the next release cycle), Meilisearch enables users to create and fine-tune vector embeddings, tailoring their search engine to specific business needs. Moreover, evolving AI models learn from user interactions, continuously improving search precision.

What‘s included in the new release package?
-------------------------------------------

The AI-enhanced hybrid search from Meilisearch leverages our existing robust search infrastructure, including advanced sorting, filtering, faceting, and geo-sorting capabilities, among others.

New release features

Cloud monitoring metrics have arrived!

We’re announcing the release of Meilisearch 1.6. Let’s dive into some of the most important changes. You can also view the [full changelog](https://github.com/meilisearch/meilisearch/releases/tag/v1.6.0) on GitHub.

<Callout>
  Meilisearch 1.6 is also available on [Meilisearch Cloud](https://cloud.meilisearch.com/login?utm_campaign=release-v1-6&utm_source=blog), including all experimental features.
</Callout>

Experimental feature: hybrid search
-----------------------------------

Meilisearch introduces hybrid search. It combines full-text and semantic search to enhance the accuracy and comprehensiveness of search results. Picture a movie app like [where2watch](https://where2watch.meilisearch.com/?utm_campaign=release-v1-6&utm_source=blog). Now, your users will be able to find those movies they can't quite name but remember the story.

Furthermore, Meilisearch now streamlines the creation of vector embeddings. Choose your preferred embedders and Meilisearch will handle all interactions with external tools for you.

### Configuring embedders

You can [configure the embedders](https://www.meilisearch.com/docs/learn/experimental/vector_search?utm_campaign=release-v1-6&utm_source=blog#generate-vector-embeddings) in your index settings. Select from three types of embedders for your needs:

`openAI`:

*   Uses the [OpenAI](https://openai.com/) API for computing embeddings
*   Requires an OpenAI API key for operation

`huggingFace`:

*   Enables local computation of embeddings by downloading models from the [HuggingFace Hub](https://huggingface.co/models)
*   Operates on your CPU–not your GPU–which may impact indexing performance

`userProvided`:

*   Functions similarly to Meilisearch v1.3, with a key difference: you must define a specific embedder
*   Allows you to add pre-computed embeddings into your documents. You perform searches using vectors instead of text.

To use hybrid search, define at least one embedder in the index settings:

```JSON
{
  "embedders": {
    "default": {
      "source":  "openAi",
      "apiKey": "<your-OpenAI-API-key>",
      "model": "text-embedding-ada-002",
      "documentTemplate": "A movie titled '{{doc.title}}' whose description starts with {{doc.overview|truncatewords: 20}}"
    },
    "image": {
      "source": "userProvided",
      "dimensions": 512
    },
    "translation": {
      "source": "huggingFace",
      "model": "sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2",
      "documentTemplate": "A movie titled '{{doc.title}}' whose description starts with {{doc.overview|truncatewords: 20}}"
    }
  }
}

```

The `documentTemplate` field acts as a blueprint for creating your document's embedding. It uses the [Liquid template language](https://shopify.dev/docs/api/liquid). While its inclusion is optional, it is highly recommended, especially since embedding models are optimized for concise texts. It keeps only the necessary content, excluding non-essential data like `id`, and helps in adding context to increase relevancy.

### **Hybrid search**

To [perform a hybrid search](https://www.meilisearch.com/docs/learn/experimental/vector_search?utm_campaign=release-v1-6&utm_source=blog#vector-search-with-auto-embeddings), use the hybrid field within the `POST /index/:index_uid/search` route.

```JSON
{
    "q": "Plumbers and dinosaurs",
    "hybrid": {
        "semanticRatio": 0.9,
        "embedder": "default"
    }
}

```

`embedder`: an embedder from the options configured in your index settings.

`semanticRatio`: a floating value ranging from `0` to `1`; `1` is a  fully semantic search; `0` is an exact, match-focused full-text search; the default is `0.5` which mixes both methods.

Your control over the semantic ratio directly influences how search results are ranked. A higher semantic ratio shifts the focus towards the context and meaning behind your query, ranking results that are more semantically relevant higher. 

On the other hand, a lower semantic ratio increases the weight given to keyword accuracy in the ranking process, bringing results that closely match your specific search terms to the forefront.

### **Breaking changes in the experimental vector search API**

Meilisearch v1.6 introduces some breaking changes in the vector search API.

Previously, you could send vectors without specifying a model. Now, you must define a model in the settings:

```JSON
"embedders": {
    "default": {
      "source": "userProvided",
      "dimensions": 512
    }
}

```

Because Meilisearch now supports multiple embedders, it has updated the vector submission format from arrays to JSON objects.

*   Previews format: `“_vectors”: [[0.0, 0.1]]`
*   New format: `“_vectors”: {“image2text”: [0.0, 0.1, …]}`

For detailed information on these updates, refer to the [documentation](https://www.meilisearch.com/docs/learn/experimental/vector_search?utm_campaign=release-v1-6&utm_source=blog).

For in-depth technical information, explore the [series of articles](__GHOST_URL__/spotify-inspired-hybrid-search-and-rust/?utm_campaign=release-v1-6&utm_source=blog) on [Arroy](https://github.com/meilisearch/arroy), an open-source repository based on [Spotify’s Annoy](https://github.com/spotify/annoy) and developed in Rust. This library, created and maintained by the Meilisearch engine team, specializes in searching for vectors in a space that are near a specified query vector.

**Performance optimization**
----------------------------

### Improved indexing speed

We're thrilled to share a major enhancement in Meilisearch's indexing performance. Our recent tests, including scenarios with frequent and partial document updates, have shown impressive results: **a reduction in indexing time by up to 50%**, and in some cases, **even as much as 75%**. 

Thanks to our latest optimizations, Meilisearch now **stores and pre-computes less data**. Additionally, during document updates, it **re-indexes or deletes only the necessary data**. For instance, in an e-commerce dataset, updating the stock level of a product results in re-indexing just the 'stock' field, rather than the entire product document.

### Disk space usage reduction

Meilisearch reduces internal data storage, leading to a more **compact database size** on your disk. With a dataset of approximately 15Mb, we observed a **40% to 50% reduction in database size**.

This enhancement not only reduces the database size, but also **improves its stability**, making the space savings more evident as the number of documents increases.

**New feature: customize proximity precision**
----------------------------------------------

To further reduce indexing speed, Meilisearch now allows you to tailor the accuracy of the [proximity ranking rule](https://www.meilisearch.com/docs/learn/core_concepts/relevancy?utm_campaign=release-v1-6&utm_source=blog#3-proximity) to your specific needs.

The proximity ranking rule is computationally demanding and may lead to longer indexing times. Reducing its accuracy can greatly enhance performance, and in most scenarios, it will not substantially affect the relevancy of the results.

To adjust its impact [configure the `proximityPrecision` setting](https://www.meilisearch.com/docs/reference/api/settings?utm_campaign=release-v1-6&utm_source=blog#proximity-precision):

```JSON
curl \
  -X PATCH 'http://localhost:7700/indexes/books/settings/proximity-precision' \
  -H 'Content-Type: application/json'  \
  --data-binary '{
    "proximityPrecision": "byAttribute"
  }'
```

The default `proximityPrecision` setting is `byWord`, which calculates proximity based on exact word distances. 

The `byAttribute` setting considers words in the same attribute as proximate, regardless of their exact distance.

Using `byAttribute` can boost the indexing speed, but it might slightly change how relevant the results are. This becomes more noticeable in searches where it's important for words to be close to each other.

For example, when you're looking through song lyrics or long articles, like trying to find 'world war' in a bunch of Wikipedia pages, you might end up with results that contain these words but not necessarily close together or in the desired order. This is also true for [phrase searches](https://www.meilisearch.com/docs/reference/api/search?utm_campaign=release-v1-6&utm_source=blog#phrase-search) and for searches involving [multi-word synonyms](https://www.meilisearch.com/docs/learn/configuration/synonyms?utm_campaign=release-v1-6&utm_source=blog#multi-word-synonyms), where the specific combination of words is crucial.

**New feature: task queue webhook**
-----------------------------------

Meilisearch now offers a webhook feature to notify a custom URL when an asynchronous task finishes (either succeeds, fails, or gets canceled).

This feature is particularly useful for streamlining workflows, saving you from polling the tasks route.

Set up your webhook at launch using these environment variables:

```bash
MEILI_TASK_WEBHOOK_URL=https://mywebsite.com/my-super-webhook?user=1234&number=8

MEILI_TASK_WEBHOOK_AUTHORIZATION_HEADER='Bearer 12340987546wowowlolol'
```

You can also use the respective command-line options.

Once set up, the webhook sends out a payload in [JSON Lines (ndjson) format](https://www.meilisearch.com/docs/learn/core_concepts/documents?utm_campaign=release-v1-6&utm_source=blog#ndjson) to your specified URL, containing the list of finished tasks:

**Experimental feature: limit the number of batched tasks**
-----------------------------------------------------------

To speed up the indexing process, Meilisearch processes similar [tasks](https://www.meilisearch.com/docs/learn/async/asynchronous_operations?utm_campaign=release-v1-6&utm_source=blog#tasks-and-asynchronous-operations) in large batches. However, excessive [queued tasks](https://www.meilisearch.com/docs/learn/async/asynchronous_operations?utm_campaign=release-v1-6&utm_source=blog#task-queue) can occasionally cause crashes or stalls.

To control the number of batched tasks, set the limit at launch using either the command-line argument `--experimental-max-number-of-batched-tasks`, the `MEILI_EXPERIMENTAL_MAX_NUMBER_OF_BATCHED_TASKS` environment variable, or the [configuration file](https://www.meilisearch.com/docs/learn/configuration/instance_options?utm_campaign=release-v1-6&utm_source=blog#configuration-file).

Meilisearch v1.6

We’re announcing the release of Meilisearch 1.5. Let’s dive into some of the most important changes.

<Callout>
  Meilisearch 1.5 is also available on [Meilisearch Cloud](https://cloud.meilisearch.com/login?utm_campaign=release-v1-5&utm_source=blog)—upgrade without any downtime now.
</Callout>

Indexing speed improvements
---------------------------

We’re excited to release the first of a series of improvements to Meilisearch’s indexing speed. 🎉

We’ve noticed **up to 25% faster indexing** depending on the use case. The performance gain is more significant on datasets containing a lot of words like wikis or ebooks.

We’ve achieved this by tweaking the settings for multiple-words queries. If you see any impact on your search relevancy, [let us know](https://github.com/orgs/meilisearch/discussions)!

<Callout>
  Take a look at the [indexing speed benchmarks](https://x.com/StriftCodes/status/1726539789401546880).
</Callout>

There’s more regarding indexing speed in version 1.6—but I don’t want to spoil anything 🤫

New feature: on-demand snapshots
--------------------------------

A [snapshot](https://www.meilisearch.com/docs/learn/advanced/snapshots?utm_campaign=release-v1-5&utm_source=blog) is a copy of your database. Snapshot files are useful to backup your database content and settings. Meilisearch 1.5 introduces the ability to create snapshots on demand.

To create a snapshot, use the [relevant SDK](https://www.meilisearch.com/docs/learn/what_is_meilisearch/sdks?utm_campaign=release-v1-5&utm_source=blog) method or the [REST API](https://www.meilisearch.com/docs/reference/api/snapshots?utm_campaign=release-v1-5&utm_source=blog). In JavaScript, create a snapshot like this:

```javascript
const client = new MeiliSearch({ /* credentials */ })
const task = await client.createSnapshot()
```
<Callout>
  You can also [schedule automatic snapshots](https://www.meilisearch.com/docs/learn/advanced/snapshots?utm_campaign=release-v1-5&utm_source=blog#creating-snapshots) on regular intervals.
</Callout>

Experimental feature: Puffin reports
------------------------------------

Puffin reports allow to get information about what’s happening in the search engine. Enabling this feature will make Meilisearch automatically export .puffin file reports. If you’re encountering performance issues, make sure to share your reports with the Meilisearch team.

This experimental feature can be enabled via the [REST API](https://meilisearch.com/docs/reference/api/experimental_features?utm_campaign=release-v1-5&utm_source=blog#configure-experimental-features):

```sh
curl \
  -X PATCH 'http://localhost:7700/experimental-features/' \
  -H 'Content-Type: application/json'  \
--data-binary '{
    "exportPuffinReports": true
  }'
```
<Callout>
  Give feedback regarding Puffin reports in this [Github discussion](https://github.com/orgs/meilisearch/discussions/693).

Meilisearch v1.5

You asked for it, and it's finally here! Search analytics has officially landed in the Meilisearch Cloud! We've received numerous [requests](https://roadmap.meilisearch.com/tabs/1-under-consideration) for a way to track key analytics in the Meilisearch Cloud, and we've been hard at work developing a solution that not only empowers you to make data-driven decisions, but also enhances the overall user experience.

So, what's all the buzz about? 🤔
---------------------------------

The new dashboard incorporates a set of metrics providing insights into your users' search behaviors. Its purpose is to give you a quick and comprehensible overview of user search queries and highlight what they might be missing. The implications are vast:

*   Improve recommendations and popular search sections, bolstering e-commerce through cross-selling.
*   Create intelligence reports for your customers.
*   Fine-tune settings and ranking rules to optimize search experiences and inform business decisions.

What metrics can you expect?
----------------------------

The first iteration of cloud analytics covers the following metrics:

*   Daily searches chart
*   Most searched queries
*   Searches without results
*   Daily search latency
*   Total searches
*   Total users
*   No result rate
*   Click through rate\*
*   Average click position
*   Daily searches per index
*   Conversion\*

\*_The CTR (click-through rate) and the conversion rate_ [_must be configured_](https://www.meilisearch.com/docs/learn/cloud/analytics?utm_campaign=analytics-v1&utm_source=blog) _to fit a specific use case or need._

The default view combines the data from the indexes per project, but it’s also possible to filter out the insights for a specific project of your choice. The dashboard also allows you to select a custom range using a date picker:

For a detailed walkthrough, check out the [live demo recording of search analytics](https://www.youtube.com/watch?v=yCQWha562M0) on our YouTube channel.

The benefits of search analytics insights
-----------------------------------------

There are numerous advantages to gaining deeper insights into how your users interact with search. With our brand-new dashboard, you can:

*   **Gain rapid, actionable insights into your search performance** at a glance.
*   **Enhance your users' experience** by continuously optimizing result relevancy.
*   **Make more informed business decisions** by understanding your users and their needs.
*   For eCommerce and marketplaces: **develop cross-selling and upselling strategies to boost conversions.**

This marks just the beginning of our optimization and insights journey. Stay tuned for v2, where we will introduce advanced analytics capabilities and subviews.

### Availability and plans

The new Cloud search analytics are available for all Cloud users across all pricing tiers. Each tier has access to the same analytics and chart functionalities of the search analytics dashboard, with the distinction occurring in the _length of data retention_ provided to each tier: 7 days for the Build plan, 30 days for the Grow plan, and 90 days for both Pro and Enterprise plans.
