启用sphinx全文搜索与实例
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:
source tmsgs { type = 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, 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 }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 ); //开源代码phpfensi测试数据 ?>[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.
Coreseek Full Text Server 3.1 Copyright (c) 2006-2008 coreseek测试数据 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.
