我如何能够增加“我”的搜索。
原标题:how could I increase the speed of my search suggest?

I add a search suggest for my site just like Google Suggest, but the speed is a litte slow ... I did it in this way: When the user type in the search bar, I use Ajax to pass the keyword to a php file, which search the keyword in the database(MySql) with statement like this:

 SELECT DISTINCT keywords
 FROM  `searchrecord` 
 WHERE keywords LIKE  $keywords%  

表格查询记录大约有500 000份。

但最后,速度几乎是无法忍受的,我不得不等待很长时间才能看到建议的语句。 你们是否建议如何加快这项工作?

最佳回答

如果在一栏上有一个指数,那么最终的询问就应该很快。 这实际上是使用指数的最佳方法。 但是,如果你在开始搜索时增加1%,你就会有效地降低你的指数速度(而且你不得不使用全文检索,这将防止案件问题)。

你们也应该检查你的询问的安全,我们都希望你在使用之前能够变换成的硬木。

如果关键词是关键词清单,那么你应询问:

WHERE keyword IN ( key1 , key2 , key3 )

或:

WHERE keyword LIKE  key1%  OR keyword LIKE  key2%  OR keyword LIKE  key3%
