php启用sphinx全文搜索的实现方法

前端之家收集整理的这篇文章主要介绍了php启用sphinx全文搜索的实现方法前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

本文实例讲述了PHP启用sphinx全文搜索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:

代码如下:

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:

代码如下:
MysqL sql_host = localhost sql_user = root sql_pass = 1 sql_db = PHPwind75sp3 sql_port = 3306 # optional,default is 3306 #sql_sock = /tmp/MysqL3307.sock sql_query_pre = SET NAMES gbk sql_query = SELECT id,name,type,stock FROM pw_tools #sql_attr_uint = id sql_attr_uint = stock }

index tmsgsindex
{
source = tmsgs
path = /var/mmseg/searchdata/beihai365
docinfo = extern
charset_type = zh_cn.gbk

min_prefix_len = 0

min_infix_len = 2

ngram_len = 2

charset_dictpath = /var/mmseg/data

min_prefix_len = 0

min_infix_len = 0

min_word_len = 2

}

indexer
{
mem_limit = 128M
}

searchd
{

listen = 3312

log = /var/log/searchd.log
query_log = /var/log/query.log
read_timeout = 5
max_children = 30
pid_file = /var/log/searchd.pid
max_matches = 1000

seamless_rotate = 1

preopen_indexes = 0

unlink_old = 1

}
source tmsgs
{
type = MysqL
sql_host = localhost
sql_user = root
sql_pass = 1
sql_db = PHPwind75sp3
sql_port = 3306 # optional,stock FROM pw_tools

sql_attr_uint = id

sql_attr_uint = stock
}
index tmsgsindex
{
source = tmsgs
path = /var/mmseg/searchdata/beihai365
docinfo = extern
charset_type = zh_cn.gbk

min_prefix_len = 0

min_infix_len = 2

ngram_len = 2

charset_dictpath = /var/mmseg/data

min_prefix_len = 0

min_infix_len = 0

min_word_len = 2

}
indexer
{
mem_limit = 128M
}
searchd
{

listen = 3312

log = /var/log/searchd.log
query_log = /var/log/query.log
read_timeout = 5
max_children = 30
pid_file = /var/log/searchd.pid
max_matches = 1000

seamless_rotate = 1

preopen_indexes = 0

unlink_old = 1

}


再看一下,测试客户端代码:
<div class="codetitle"><a style="CURSOR: pointer" data="754" class="copybut" id="copybut754" onclick="doCopy('code754')"> 代码如下:
<div class="codebody" id="code754"><?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:
<div class="codetitle"><a style="CURSOR: pointer" data="40275" class="copybut" id="copybut40275" onclick="doCopy('code40275')"> 代码如下:
<div class="codebody" id="code40275">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
(

)

)

(

)
)

[time] => 0.018
[words] => 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.

Coreseek Full Text Server 3.1 Copyright (c) 2006-2008 coreseek.com using config file './csft.conf'... 1, pt:1,1; index 'tmsgsindex': query 'App ': returned 0 matches of 0 total in 0.017 sec words: 1. 'app': 0 documents,0 hits 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。
