本文介绍了一种使用SQLite的FTS3模块实现Android应用快速全文检索的方法。通过创建虚拟表并定期更新来维护索引，提高文本查询效率。需要注意的是，对于中文支持还需要额外的调整。

用户反映app文本查询很慢

确实做程序的时候也没多想偷懒啦

文本查询就一行接一行做 indexOf 查询比较慢。

不要自己开发全文检索啦(嘿嘿不会)

网上找了android全文检索的资料

主要是SQLite和android 支持

SQLite contains full-text search module called FTS3, using this module you can easily add fast full text search to an Android application.
First you need to create virtual table:

1. CREATE VIRTUAL TABLE TableName

2. USING FTS3(ColOne TEXT, ColTwo DATETIME)

Your table must contains at least 1 TEXT field.
The FTS3 virtual table acts like a regular table, but you need to manually maintain the indexes to keep referential integrity — you should UPDATE the FTS3 table from time to time.
The full-text query in SQLite looks like this:

1. SELECT * FROM TableName WHERE ColOne MATCH 'search phrase'

Make sure you use MATCH instead of equals or LIKE to scan a TEXT column in a virtual table.

回头修改哈哈

PS 某牛发表的回复中文支持不是太好
FTS3 needs to be hacked to support splitting chinese texts.
