Meilisearch v1.13 release notes - Meilisearch Documentation

New Features

AI-powered search is now stable and enabled by default

AI-powered search is available to all users by default and no longer requires manual activation. Vector search, semantic search, and hybrid search capabilities are now production-ready.

Dumpless upgrades

Upgrade to new Meilisearch releases without generating a dump file. Use the --experimental-dumpless-upgrade flag when starting Meilisearch after updating the binary:

./meilisearch --experimental-dumpless-upgrade

This faster and more efficient process replaces the traditional dump-based upgrade method.

Warning: Meilisearch recommends generating a backup snapshot before upgrading. This is an experimental feature, and failed upgrades may lead to database corruption.

Remote federated search requests

Query multiple Meilisearch instances simultaneously using the /multi-search route. This is particularly useful when handling very large databases. First, enable the network experimental feature:

curl \
 -X PATCH 'MEILISEARCH_URL/experimental-features/' \
 -H 'Content-Type: application/json' \
 --data-binary '{"network": true}'

Next, configure your network by setting up one self instance and multiple remotes using the /network endpoint:

curl \
 -X PATCH 'MEILISEARCH_URL/network/' \
 -H 'Content-Type: application/json' \
 --data-binary <<'EOF'
{
 "remotes": {
 "ms-0": {
 "url": "http://ms-1235.example.meilisearch.io",
 "searchApiKey": "Ecd1SDDi4pqdJD6qYLxD3y7VZAEb4d9j6LJgt4d6xas"
 },
 "ms-1": {
 "url": "http://ms-4242.example.meilisearch.io",
 "searchApiKey": "hrVu-OMcjPGElK7692K7bwriBoGyHXTMvB5NmZkMKqQ"
 }
 },
 "self": "ms-0"
}
EOF

Repeat this process with every instance in your network. Do not send the same documents to different instances. Finally, make a /multi-search query with the new federationOptions.remote parameter:

curl \
 -X PATCH 'MEILISEARCH_URL/multi-search/' \
 -H 'Content-Type: application/json' \
 --data-binary <<'EOF'
{
 "federation": {},
 "queries": [
 {
 "q": "Batman returns dark",
 "indexUid": "movies",
 "federationOptions": {
 "remote": "ms-0"
 }
 },
 {
 "q": "Batman returns dark",
 "indexUid": "movies",
 "federationOptions": {
 "remote": "ms-1"
 }
 }
 ]
}
EOF

Improvements

Enhanced monitoring and performance insights

New usedDatabaseSize field on the /stats route to track actual database usage
Embeddings information now exposed on the /stats route
Prometheus metrics added to measure task queue latency
Faster listing of indexes
Improved task auto-batching with ability to limit total batch size

Better error messages

Improved error message when an attribute is not filterable, making it easier to debug search configuration issues.

Other

Breaking changes

vectorStore is no longer an accepted value for the /experimental-features route
Ollama URLs must end with either /api/embed or /api/embeddings
Error codes have been refined:
invalid_embedder has been split into invalid_search_embedder and invalid_similar_embedder for search and similar endpoints
invalid_hybrid_query has been renamed to invalid_search_hybrid_query
