Meilisearch v1.5 introduces improvements in indexing speed and the possibility of triggering snapshots on demand.

🧰 All official Meilisearch integrations (including SDKs, clients, and other tools) are compatible with this Meilisearch release. Integration deployment happens between 4 to 48 hours after a new version becomes available.

Some SDKs might not include all new features—consult the project repository for detailed information. Is a feature you need missing from your chosen SDK? Create an issue letting us know you need it, or, for open-source karma points, open a PR implementing it (we'll love you for that ❤️).

New features and improvements 🔥

Indexing speed improvements

v1.5 improves indexing speed for text-heavy datasets. Datasets with fields containing more than 100 words should see a reduction of 5% to 20% to indexing times, with gains proportional to the amount of words in a document.

This might result in minor impact to search result relevancy for queries containing 4 words or more. Contact us in our GitHub Discussions page if this is significantly affecting your application.

Indexing speed improvements might not be visible in datasets with fewer than 20 words per field, regardless of how many fields each document contains.

Snapshots on-demand

This release introduces a new /snapshots API route for creating snapshots on demand:

curl -X POST HTTP://localhost:7700/snapshots

This route returns a summarized task object.

By default, Meilisearch creates snapshots inside the /snapshots directory. You can customize this directory with the --snapshot-dir configuration option.

Done by @irevoire in #4051.

Experimental feature: Export Puffin reports

This experimental feature allows Meilisearch to automatically export .puffin reports. .puffin files provide information on Meilisearch's internal processes and may be useful when diagnosing performance issues.

Use the /experimental-features endpoint to activate this feature:

curl \
  -X PATCH 'http://localhost:7700/experimental-features/' \
  -H 'Content-Type: application/json'  \
  --data-binary '{
    "exportPuffinReports": true
  }'

📣 Consult the GitHub discussion for more information.

Other improvements

• The experimental /metrics route can now be activated via HTTP. Done by @braddotcoffee with the review of @vivek-26 in #4126. ⚠️ Avoid using CLI flag and the API at the same time when managing experimental features.
• Add Khmer language support (#4169 and meilisearch/charabia#203) @xshadowlegendx and @ManyTheFish
• Integrate the meilitool command line interface into the meilisearch Docker image (#4167) @Kerollmops This tool provides commands to enforce the cancellation of tasks and the creation of dumps for stuck Meilisearch instances. In the running Meilisearch container, just do meilitool --help to get the usage.
