Warning

Meilisearch v1.13 introduces several significant improvements, including stabilizing the Vector Store feature for seamless hybrid search integration! 🎉 This version also simplifies the Meilisearch upgrade process: you don't need a dump for migrating anymore!

New features and updates 🔥

Stabilize Vector Store feature

After its initial release in v1.3.0, we have now fully stabilized the Vector Store feature. The experimental feature no longer requires manual activation, and the vectorStore field is no longer displayed or accepted by the /experimental-features route. This makes it even simpler to utilize our hybrid search capability, which delivers significantly better search relevance by combining traditional full text search with AI-powered semantic search.

Breaking Changes before Stabilization

• Accepted Ollama URLs can only end with /api/embed and /api/embeddings.
• Modified error codes:
  • invalid_embedder has been split into invalid_search_embedder and invalid_similar_embedder. These codes are returned when the embedder parameter of a search (resp. similar) request refers to a non-existing embedder configuration or is not a string.
  • invalid_hybrid_query has been renamed to invalid_search_hybrid_query. It is returned when the hybrid parameter is invalid: contains unknown keys or is not either null or an object.

Experimental Dumpless Upgrade: Ease upgrading to the next version without a dump

From now on you can upgrade any database in the v1.12 version or more to the latest version without using a dump.
That means it's an in-place, way faster upgrade process that consumes only the minimal amount of RAM or disk required.

To upgrade your v1.12 database to v1.13 runs:

./meilisearch --experimental-dumpless-upgrade
