怎么在php項目中啟用sphinx全文搜索功能

怎么在php項目中啟用sphinx全文搜索功能？相信很多沒有經驗的人對此束手無策，為此本文總結了問題出現的原因和解決方法，通過這篇文章希望你能解決這個問題。

在編譯安裝 sphinx 的時候出現很多中文亂碼,最后拋出錯誤卡住了,我去到官方直接下載一個 rpm 包,安裝就很爽,具體錯誤不想研究了,忙開發呢.

安裝兩個包,一個是 mmseg 這個是生成中文字典的程序,一個是  csft 也就是中國版的sphinx .

rpm -ivh 安裝完以后,很順利~~不到半分鐘就裝完了.

中文字典庫,我直接去 csft 官方下載了,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關鍵字.

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 這個就是sphinx 認識的字典了.

放哪里？放你在 sphinx.conf 里面配置的字典路徑里面,等會說到,然后基本就差不多了,在看下sphinx 幾個實用的程序:

復制代碼 代碼如下:

[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  是測試搜索是否生效用的，也很好用，不如我還沒用客戶端腳本開發，就可以用這個來查看全文搜索是否成功

csft-searchd  這個就是 sphinx 搜索的守護程序了。 啟動以后，就可以用腳本 php python 等，開查詢了。

就那么簡單,在看下關鍵的兩部分東西.

sphinx.conf 配置文件:

復制代碼 代碼如下:

        #seamless_rotate                     = 1
        #preopen_indexes                     = 0
        #unlink_old                          = 1
}

再看一下,測試客戶端代碼:

復制代碼 代碼如下:

<?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”這個關鍵字是我自己手動在字典里面添加的,看是否能真的搜到,實例代碼如下:

復制代碼 代碼如下:

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
                )
        )
)

完全沒問題,搜索出來了,幾個關鍵的操作:
[root@beihai365 /]# csft-searchd --stop 停止搜索守護

[root@beihai365 /]# csft-indexer --all 針對所有節點生成索引,你也可以針對某個節點生成索引比如:csft-indexer  xx

[root@beihai365 /]# csft-search App 搜索關鍵字 App,不過看下面信息沒有搜到和沒有命中任何的文檔.

Coreseek Full Text Server 3.1

using config file './csft.conf'...

pt:1, 1;        index 'tmsgsindex': query 'App ': returned 0 matches of 0 total in 0.017 sec
words:

當大家在運行這些命令的時候發現,需要你自己手動的置頂 --config  sphinx.conf   配置文件的路徑,很不方便,所以我干脆 ln -s 一個在 ./,這樣不用每次都去敲入  --config.
