windows安装sphinx3.0.1(中文检索)

sphinx的简介就不多说，请直接查看文档

1.从spinx官网下载最新版的sphinx 解压。

地址：http://www.sphinxsearch.com/

2.新建data 和 log 目录

3.新建sphinx.conf配置文件 放在bin目录 下

配置项的信息可以参考etc/sphinx.conf.dist 非常全面。

4.生成索引文件

5.启动searchd服务。

6.用api实现全文搜索

<?php
require ( "sphinxapi.php" );
$cl = new SphinxClient ();
$q = "我要好好学学"; //模拟关键字
$sql = "";
$mode = SPH_MATCH_ALL;
$host = "127.0.0.1";
$port = 9312;
$index = "*";
$cl->SetServer ( $host, $port );
$cl->SetConnectTimeout(10);
$cl->SetArrayResult(true);
$cl->SetMatchMode(SPH_MATCH_ALL);
$res = $cl->Query ( $q, $index );
var_dump($res['matches']);

sphinx搜索只是查询sphinx索引，并不查询mysql，从sphinx服务中查询出的id就是mysql 数据库中的主键。根据主键查询mysql。当数据库中的内容发生改变后，要重新生成索引，或者在数据表中添加一个字段用来标记该条数据是否生成了索引，重建索引时，只生成没有生成索引的记录，然后合并到索引中去即可
