Sphinx 全文检索引擎

Sphinx是一个基于SQL的全文检索引擎,可以结合MySQL,PostgreSQL做全文搜索,它可以提供比数据库本身更专业的搜索功能,使得应用程序更容易实现专业化的全文检索。Sphinx特别为一些脚本语言设计搜索API接口,如PHP,Python,Perl,Ruby等,同时为MySQL也设计了一个存储引擎插件。


继sphinx 2.3.1-beta 发布之后一年半时间,sphinx终于发布了sphinx 2.3.2-beta 

之前的sphinx 2.3.1-beta 做出了重大改进,比如线程池,可以充分利用多核CPU 。

此次2.3.2-beta 值得注意的新特性是启动速度超快,不再等待全部索引从缓慢的硬盘逐步载入内存后才能启动完成。

主要更新内容:

  • Searchd now uses mmap(). Daemon is available immediately and spawns a separate thread that loads the indexes.

  • daemon now picks changed index path when it receives HUP

  • added SphinxQL support for comparison, IN, and BETWEEN conditions over ANY/ALL(mva)

  • added explicit JSON type conversion in WHERE clause

Bug fixes

  • fixed #2516 suggest for index with exact_word or morphology options

  • fixed #2507 .NET Connector overflow exception (unsigned id support)

  • Fixed initial round-robin counter

  • fixed #2502 final calculation of expression at RT index (optimized calls count)

这次更新修复了超过100个bug,某些最重要的是有关查询缓存的。
