Meilisearch v1.14 (to be released on April 14th 2025) introduces composite embedders:

• A new source of embedders called "composite", with two new parameters: searchEmbedder and indexingEmbedder, to specify two embedders to be used respectively at search/indexing time.
• Please refer to public usage for details

How to use the feature?

Please refer to the public API page

What is an experimental feature

By enabling this feature via the /experimental-features route, you opt into the following:

• The API and the behavior of the way composite embedders are declared and work can break between two minor versions of Meilisearch.
• The feature could be removed altogether in a future minor version of Meilisearch

You can use this feature in production, but be prepared to update your code from one version to the next.

Why is this feature not stable yet?

• We are refining the API and making sure it's not too complex or too simple
• We are testing the performance of local embedders in a variety of real-life scenarios

🗣️ You are welcome to give feedback about the score details or ask any question on its usage; we are eager to collect feedback on the feature

⚠️ Disabling the feature

To fully disable the feature, you need to delete all the composite embedders in you embedders settings. To remove an embedder, set it to null in a PATCH settings call: { "embedders: { "YOUR_EMBEDDER_NAME": null } }.

When all composite embedders have been removed from all indexes, call the experimental feature route to set compositeEmbedders to false.
