meilisearch v1.49.0 版本更新介绍

发布日期: 2026-07-06
版本号: v1.49.0

Meilisearch更新了同义词存储机制，通过改变存储和检索方式实现懒加载，仅在查询匹配同义词时才加载，从而解决了之前同义词数量多时的性能问题，性能提升最高可达13倍。此外，修复了排名分数损坏后的工作流问题，并使OpenAPI规则对返回202状态码的路由要求不那么严格。

更新内容（中文）

由 @Kerollmops 在 https://github.com/meilisearch/meilisearch/pull/6466 中改进同义词存储我们通过改变查询处理过程中存储和检索同义词的方式来提升性能。用户可能在同义词数量较多时遇到性能问题，这会对搜索性能造成显著影响。Meilisearch 支持团队曾建议将设置和同义词作为关键词移至专用文档。该问题现已解决：同义词采用惰性加载机制，仅在匹配到特定词汇时才会载入。根据同义词数量不同，最高可实现 13 倍的性能提升。

Improve the synonyms storage by @Kerollmops in https://github.com/meilisearch/meilisearch/pull/6466 We improve synonyms’ performance by changing how we store and retrieve them during query processing. Users may have experienced performance issues when the number of synonyms in an index was high, resulting in a significant impact on search performance. The Meilisearch support team advised moving the settings and synonyms-as-keywords to the dedicated documents. This is no longer an issue; synonyms are loaded lazily, only when a word matches a synonym. You can see performance improvements of up to 13x, depending on the number of synonyms.
