Meilisearch v1.41 release notes - Meilisearch Documentation

New Features

Dynamic Search Rules with pinning

Introduce the Dynamic Search Rules (DSR) experimental feature, making it easy to promote the right content for the right searches with flexible, condition-based pinning. In this first version, rules can be triggered by query-based conditions such as empty queries or literal substring matches, as well as time windows. Multiple documents can be pinned in a defined order, and pins still work with filtering, pagination, facet distribution, hybrid search, and federated search. Rules can be created or updated with PATCH /dynamic-search-rules/{uid} and removed with DELETE /dynamic-search-rules/{uid}. In this first version, a rule can define query- or time-based conditions and pin specific documents at fixed positions in the results list. Example of rule creation/update:

{
  "description": "Promote featured products for wireless headphone searches",
  "active": true,
  "conditions": [
    {
      "scope": "query",
      "contains": "headphone"
    }
  ],
  "actions": [
    {
      "selector": {
        "indexUid": "products",
        "id": "featured-headphones-001"
      },
      "action": {
        "type": "pin",
        "position": 0
      }
    },
    {
      "selector": {
        "indexUid": "products",
        "id": "featured-headphones-002"
      },
      "action": {
        "type": "pin",
        "position": 1
      }
    }
  ]
}

Improvements

Network enabled by default in sharded instances

When network.leader is set in the instance, useNetwork now defaults to true in search requests when omitted. This allows you to naturally query all documents in a sharded context without explicitly requesting network searches. Search requests now automatically use the network when replicated sharding is enabled, ensuring all shards are covered exactly once. When network.leader is not present (particularly when no network is defined), the behavior remains identical to previous versions.

`useNetwork` optimizes shard selection

To prevent unnecessary network activity, when deciding which remote to ask for a shard in a network search, Meilisearch will now always pick the local instance if it owns the shard.

More efficient FST building

The construction of the word FST (word dictionary) has been improved by removing the need for a full scan of the word docids database. This drastically improves database performance when inserting a large number of documents, even when inserting only a few. Find more information on GitHub
