数据表
1、documents
CREATE TABLE `documents` (
`id` int(13) NOT NULL auto_increment,
`group_id` int(11) NOT NULL,
`group_id2` int(11) NOT NULL,
`date_added` datetime NOT NULL,
`title` varchar(255) NOT NULL,
`content` text NOT NULL,
PRIMARY KEY (`id`),
KEY `title` (`title`),
FULLTEXT KEY `content` (`content`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=500006 ;
2、Sphinx
CREATE TABLE `sphinx` (
`id` int(13) NOT NULL,
`weight` int(11) NOT NULL,
`query` varchar(255) NOT NULL,
KEY `Query` (`query`)
) ENGINE=SPHINX DEFAULT CHARSET=utf8;
本次测试,在sphinx.conf中共建立三个索引。
1、dramx 对 documents表的title、content字段均建立索引。
2、dramx_title 对 documents表的title字段建立索引。
3、dramx_content 对 documents表的content字段建立索引。
三个索引在具体测试时,分别被用到。
程序调用Sphinx全文检索引擎有两种方式:
一、Php调用 API
二、安装SphinxSE.
安装方法:
1、 在官网下载mysql-5.0.45-sphinxse-r871-win32.zip解压。
2、 停掉本地mysql所有服务。并将解压后的文件覆盖到mysql相应目录。
3、 启动mysql ,建立一个至少含有三个字段的表(sphinx),字段数据类型依次是int、int、varchar,
Storage Engine选择sphinx即可。
4、 查询时结合表sphinx进行联合查询。
下面先将php+mysql和 Php+ Sphinx 通过like 、order by 、group by进行测试比较。最后单独给出使用第二种方法SphinxSE的查询测试。
测试环境:
内存:1GB 、CPU:intel pentium(R) dual CPU E2140
数据量:50万条

针对php+mysql的查询,mysql-nt进程占用CPU的峰值最高到50%, 一般在20%之间,而php+Sphinx由于查询时根本没有用到mysql引擎而是查询自身的索引引擎,所以,在查询上CPU的占用可以忽略。
