PHP基于Sphinx+Swcs中文分词的全文的检索
2024-09-22 15:17:11
简介
Sphinx是开源的搜索引擎，它支持英文的全文检索。所以如果单独搭建Sphinx，你就已经可以使用全文索引了
但是有些时候我们还要进行中文分词所有scws就出现了，我们也可以使用Coreseek来建立中文索引，而Coreseek的内核就是Sphinx
1、环境
PHP 5.5.23+centos 6.5+mysql Ver 14.14 Distrib 5.1.73
2、安装sphinx
cd /usr/local/src
wget http://sphinxsearch.com/files/sphinx-2.3.1-beta.tar.gz
tar -zxf sphinx-2.3.1-beta.tar.gz
cd sphinx-2.3.1-beta
./configure --prefix=/usr/local/sphinx --with-mysql=/usr/local/mysql
./configure --prefix=/usr/local/sphinx --with-mysql-includes=/usr/include/mysql/ --with-mysql-libs=/usr/lib/mysql/
make && make install
第一种配置：如果mysql安装时候使用源码包
第二种配置：如果mysql安装的时候使用yum
3、安装sphinxclient
cd /usr/local/src/sphinx-2.3.1-beta/api/libsphinxclient/
./configure --prefix=/usr/local/sphinx/libsphinxclient
make && make install
4、安装pecl扩展sphinx
wget https://pecl.php.net/get/sphinx-1.3.3.tgz
tar -zxf sphinx-1.3.3.tgz
cd sphinx-1.3.3
phpize
./configure --with-sphinx=/usr/local/sphinx/libsphinxclient --with-php-config=php-config
make && make install
echo extension=sphinx.so > /etc/php.d/sphinx.ini
5、安装scws及pecl扩展
wget http://www.xunsearch.com/scws/down/scws-1.2.2.tar.bz2
tar -jxf scws-1.2.2.tar.bz2
cd scws-1.2.2
./configure --prefix=/usr/local/scws/
make && make install
cd ./phpext/
phpize
./configure --with-php-config=php-config
make && make install echo extension = scws.so > /etc/php.d/scws.ini
echo scws.default.charset = utf-8 >> /etc/php.d/scws.ini
echo scws.default.fpath = /usr/local/scws/etc >> /etc/php.d/scws.ini
6、安装词库
wget http://www.xunsearch.com/scws/down/scws-dict-chs-utf8.tar.bz2
tar xvjf scws-dict-chs-utf8.tar.bz2 -C /usr/local/scws/etc/
chown www:www /usr/local/scws/etc/dict.utf8.xdb
7、创建数据库并写入信息
DROP TABLE IF EXISTS `userinfo`;
CREATE TABLE `userinfo` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`userid` int(11) unsigned NOT NULL DEFAULT '0',
`addtime` datetime NOT NULL,
`post` varchar(20) NOT NULL DEFAULT '',
`summary` text NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=17 DEFAULT CHARSET=utf8; LOCK TABLES `userinfo` WRITE;
INSERT INTO `userinfo` VALUES
(NULL,1,'2012-06-01 00:24:54','运维总监','运维'),
(NULL,2,'2014-08-19 10:24:54','大客户经理','客户'),
(NULL,3,'2015-08-01 12:24:54','高级DBA工程师','DBA'),
(NULL,4,'2013-08-01 00:24:54','高级PHP工程师','PHP');
UNLOCK TABLES; DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`username` varchar(20) NOT NULL DEFAULT '',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8; LOCK TABLES `users` WRITE;
INSERT INTO `users` VALUES
(NULL,'张三'),
(NULL,'张四'),
(NULL,'李四'),
(NULL,'王五');
UNLOCK TABLES;
8、配置sphinx
source users

10、启动sphinx
pkill searchd
/usr/local/sphinx/bin/indexer --config /usr/local/sphinx/etc/sphinx.conf --all
/usr/local/sphinx/bin/searchd --config /usr/local/sphinx/etc/sphinx.conf
11、测试
<?php
$key = "张三";
$index = "users"; $so = scws_new();
$so->set_charset('utf-8');
$so->add_dict(ini_get('scws.default.fpath') . '/dict.utf8.xdb');
$so->set_rule(ini_get('scws.default.fpath') . '/rules.utf8.ini');
$so->set_ignore(true);
$so->set_multi(false);
$so->set_duality(false);
// $so->add_dict('./dd.txt',SCWS_XDICT_TXT); $so->send_text($key);
$words_array = $so->get_result();
$words = "";
foreach($words_array as $v)
{
$words = $words.'|('.$v['word'].')';
} //加入全词
#$words = '('.$key.')'.$words;
$words = trim($words,'|');
$so->close();
echo '<p>输入：'.$key.'</p>';
echo '<p>分词：'.$words.'</p>'; $sc = new SphinxClient();
$sc->SetServer('127.0.0.1',9312);
#$sc->SetMatchMode(SPH_MATCH_ALL);
$sc->SetMatchMode(SPH_MATCH_EXTENDED);
$sc->SetArrayResult(TRUE);
$res = $sc->Query($words,$index);
print_r($res);
