Meilisearch v1.47.0

🌈 Enhancements

Search personalization on federated search

We now support using the search personalization feature on federated search requests.

Like page/hitPerPage or limit/offset, the personalization option must be specified in the federation attribute to work properly. Otherwise, an error will be returned reminding you to move the attribute in federation.

The new settings indexer is feature complete 🎉

• We now better support the tokenizer-related settings
• We improved the quality of the new settings indexer to enhance the engine's performance when changing the locales, the dictionary, synonyms, stop words, separator, and non-separator tokens.
• This makes the new settings indexer feature-complete, meaning that, unless you set the MEILI_EXPERIMENTAL_NO_EDITION_2024_FOR_SETTINGS environment variable to true, all settings tasks can now be handled by the new settings indexer, bringing a better scaling behavior, much faster cancellation, and a more precise progress view.

Observability improvements

We expose more Prometheus metrics to improve observability, specifically to show more metrics on document throughput and ease debugging.

🔩 Misc. changes

Search implementation refactor

Refactor the search pipeline to mutualize the code. The new implementation will always perform a federated search under the hood, and then the output will be transformed into the expected route's output.

Noticeable changes from the user perspective:

• Some error messages have been modified
• Small breaking change: a few error codes change, such as MultiSearch<Error> <--> Search<Error>
