php啟用sphinx全文搜索的實(shí)現(xiàn)方法
文章主要介紹了php啟用sphinx全文搜索的實(shí)現(xiàn)方法,詳細(xì)講述了sphinx相關(guān)的配置與使用技巧,具有一定的參考借鑒價(jià)值,需要的朋友可以參考下。
本文實(shí)例講述了php啟用sphinx全文搜索的實(shí)現(xiàn)方法。分享給大家供大家參考。具體分析如下：
在編譯安裝 sphinx 的時(shí)候出現(xiàn)很多中文亂碼,最后拋出錯(cuò)誤卡住了,我去到官方直接下載一個(gè) rpm 包,安裝就很爽,具體錯(cuò)誤不想研究了,忙開(kāi)發(fā)呢.
安裝兩個(gè)包,一個(gè)是 mmseg 這個(gè)是生成中文字典的程序,一個(gè)是 csft 也就是中國(guó)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(kù),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(guān)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(gè)就是sphinx 認(rèn)識(shí)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(huì)說(shuō)到,然后基本就差不多了,在看下sphinx 幾個(gè)實(shí)用的程序:
復(fù)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(cè)試搜索是否生效用的，也很好用，不如我還沒(méi)用客戶(hù)端腳本開(kāi)發(fā)，就可以用這個(gè)來(lái)查看全文搜索是否成功
csft-searchd 這個(gè)就是 sphinx 搜索的守護(hù)程序了。 啟動(dòng)以后，就可以用腳本 php python 等，開(kāi)查詢(xún)了。
就那么簡(jiǎn)單,在看下關(guān)鍵的兩部分東西.
sphinx.conf 配置文件:
復(fù)制代碼 代碼如下:
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,測(cè)試客戶(hù)端代碼:
復(fù)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(gè)關(guān)鍵字是我自己手動(dòng)在字典里面添加的,看是否能真的搜到,實(shí)例代碼如下:
復(fù)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
)
)
)

[matches] => Array

[time] => 0.018

(

(

)
)
)
完全沒(méi)問(wèn)題,搜索出來(lái)了,幾個(gè)關(guān)鍵的操作:
[root@beihai365 /]# csft-searchd --stop 停止搜索守護(hù)
[root@beihai365 /]# csft-indexer --all 針對(duì)所有節(jié)點(diǎn)生成索引,你也可以針對(duì)某個(gè)節(jié)點(diǎn)生成索引比如:csft-indexer xx
[root@beihai365 /]# csft-search App 搜索關(guān)鍵字 App,不過(guò)看下面信息沒(méi)有搜到和沒(méi)有命中任何的文檔.
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
當(dāng)大家在運(yùn)行這些命令的時(shí)候發(fā)現(xiàn),需要你自己手動(dòng)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(gè)在 ./,這樣不用每次都去敲入 --config.
希望本文所述對(duì)大家的php程序設(shè)計(jì)有所幫助。
