推荐答案

您可能要考虑使用全文搜索引擎并发出SELECT ...匹配查询来代替。请注意，您需要启用FTS引擎（它是默认禁用），并创建虚拟表，而不是常规表。你可以阅读更多关于它这里。

You might want to consider using the full-text search engine and issuing SELECT...MATCH queries instead. Note that you need to enable the FTS engine (it's disabled by default) and create virtual tables instead of regular tables. You can read more about it here.
