这篇文章主要介绍了php启用sphinx全文搜索的实现方法,详细讲述了sphinx相关的配置与使用技巧,具有一定的参考借鉴价值,需要的朋友可以参考下

本文实例讲述了php启用sphinx全文搜索的实现方法。分享给大家供大家参考。具体分析如下：

在编译安装 sphinx 的时候出现很多中文乱码,最后抛出错误卡住了,我去到官方直接下载一个 rpm 包,安装就很爽,具体错误不想研究了,忙开发呢.

安装两个包,一个是 mmseg 这个是生成中文字典的程序,一个是  csft 也就是中国版的sphinx .

rpm -ivh 安装完以后,很顺利~~不到半分钟就装完了.

中文字典库,我直接去 csft 官方下载了,挺好的想得很周到.

unigram.txt  uni.lib

unigram.txt  字典文本,可以在里面添加你自己的关键字.

然后使用:mmseg -u unigram.txt 生成字典文件:unigram.txt.uni 然后重命名一下  uni.lib 这个就是sphinx 认识的字典了.

放哪里？放你在 sphinx.conf 里面配置的字典路径里面,等会说到,然后基本就差不多了,在看下sphinx 几个实用的程序:

[root@beihai365 /]# csft-

csft-indexer  csft-search   csft-searchd

csft-indexer  是生成全文搜索索引的 程序

csft-search  是测试搜索是否生效用的，也很好用，不如我还没用客户端脚本开发，就可以用这个来查看全文搜索是否成功

csft-searchd  这个就是 sphinx 搜索的守护程序了。 启动以后，就可以用脚本 php python 等，开查询了。

就那么简单,在看下关键的两部分东西.

sphinx.conf 配置文件:

        #unlink_old                          = 1 
}

再看一下,测试客户端代码:

<?php    
    header("Content-type:text/html;charset=utf-8");    
    include 'sphinxapi.php';    
    $cl = new SphinxClient();    
    $cl->SetServer('localhost',3312);    
    $cl->SetMatchMode(SPH_MATCH_ALL);    
    $cl->SetArrayResult(true);    
    $res = $cl->Query("名卡","*");    
    print_r($res);    
?>   
<?php 
header("Content-type:text/html;charset=utf-8"); 
include 'sphinxapi.php'; 
$cl = new SphinxClient(); 
$cl->SetServer('localhost',3312); 
$cl->SetMatchMode(SPH_MATCH_ALL); 
$cl->SetArrayResult(true); 
$res = $cl->Query("名卡","*"); 
print_r($res); 
?>

“名卡”这个关键字是我自己手动在字典里面添加的,看是否能真的搜到,实例代码如下:

Array    
(    
    [error] =>     
    [warning] =>     
    [status] => 0    
    [fields] => Array    
        (    
            [0] => name    
            [1] => type    
        )    
   
    [attrs] => Array    
        (    
            [stock] => 1    
        )    
   
    [matches] => Array    
        (    
            [0] => Array    
                (    
                    [id] => 8    
                    [weight] => 1    
                    [attrs] => Array    
                        (    
                            [stock] => 100    
                        )    
                )    
        )    
    [total] => 1    
    [total_found] => 1    
    [time] => 0.018    
    [words] => Array    
        (    
            [名卡] => Array    
                (    
                    [docs] => 1    
                    [hits] => 1    
                )    
        )    
)   
Array 
( 
    [error] =>  
    [warning] =>  
    [status] => 0 
    [fields] => Array 
        ( 
            [0] => name 
            [1] => type 
        ) 
    [attrs] => Array 
        ( 
            [stock] => 1 
        ) 
    [matches] => Array 
        ( 
            [0] => Array 
                ( 
                    [id] => 8 
                    [weight] => 1 
                    [attrs] => Array 
                        ( 
                            [stock] => 100 
                        ) 
                ) 
        ) 
    [total] => 1 
    [total_found] => 1 
    [time] => 0.018 
    [words] => Array 
        ( 
            [名卡] => Array 
                ( 
                    [docs] => 1 
                    [hits] => 1 
                ) 
        ) 
)

完全没问题,搜索出来了,几个关键的操作:
[root@beihai365 /]# csft-searchd --stop 停止搜索守护

[root@beihai365 /]# csft-indexer --all 针对所有节点生成索引,你也可以针对某个节点生成索引比如:csft-indexer  xx

[root@beihai365 /]# csft-search App 搜索关键字 App,不过看下面信息没有搜到和没有命中任何的文档.

当大家在运行这些命令的时候发现,需要你自己手动的置顶 --config  sphinx.conf   配置文件的路径,很不方便,所以我干脆 ln -s 一个在 ./,这样不用每次都去敲入  --config.

希望本文所述对大家的php程序设计有所帮助。
