Sphinx是一个基于SQL的全文检索引擎;普遍使用于很多网站;但由于中英文的差异,其本身,对中文的支持并不好。
主要体现在对一段话断词;英文只需按照空格对其分词即可;但对于博大精深的中文来说,却是件困难的事情。
分词在两个地方会用到;
1、索引时,根据分词索引原始数据
2、搜索时,对用户输入分词,到索引中查询
本文提供了三种目前最常用的方案Coreseek、Sphinx-for-chinaese、Sphinx+Scws,并对其简单对比;在合适的场景,选择合适的方案,得出最优的解。
评测:
一、Coreseek 为国人基于Sphinx开发的方案,目前最稳定版,是基于经典的Sphinx0.9.9版
优点:有成熟的文档、以及社区;其分词mmseg为目前国内最为好用分词,索引和搜索分词都可以用到;
缺点:深度开发、版本更新较慢;索引较慢
策略:一个词库管理后台,维护词库;定期生成字典;此套件会自动分词索引;
适用场景:普通青年、搭建差不多的搜索,适用于普遍网站
二、Sphinx-for-chinaese 为国人2基于经典的Sphinx0.9.9版开发的扩展版
优点:部署简单,易操作,内嵌分词和词库,索引和搜索分词都可以用到;
缺点:版本更新较慢;分词较弱;索引相对较慢
策略:同一
适用场景:普通青年、快速搭建搜索的小站
三、Sphinx+Scws 为两套独立系统,单独部署,所谓高内聚低耦合,强烈推荐
优点:两套系统,相对独立,各自单独Server;分词可以做其他用途;版本更新较快;
缺点:部署稍复杂,使用稍复杂;索引分词只能用一元分词,数据量较大
策略:词库管理外;使用时,先调用分词服务,后调用搜索
适用场景:文艺青年、搭建像样点的搜索;好吧文艺青年
由于本人强烈推荐方案三,对方案三有详细描述,其他方案仅提供简单部署方式。
三种方案具体实现如下:
一、coreseek
=======================================================================================================
官网 http://www.coreseek.cn
基础库 http://ftp.gnu.org/gnu/automake/
1、安装
1.0 基础库
#设置路径和中文环境:
export PATH=/usr/local/bin:$PATH
export LC_ALL=zh_CN.UTF-8
export LANG=zh_CN.UTF-8
#依赖包安装顺序
m4、autoconf、automake、libtool
./configure –prefix=/usr/local
make && make install
1.1 安装mmseg
./bootstrap
./configure –prefix=/opt/server/mmseg
make
make install
1.2 安装csft
sh buildconf.sh
./configure –prefix=/opt/server/coreseek –without-unixodbc –with-mmseg=/opt/server/mmseg –with-mmseg-includes=/opt/server/mmseg/include/mmseg/ –with-mmseg-libs=/opt/server/mmseg/lib/ –with-mysql=/opt/server/mysql
make
mkae install
1.3 配置
mv csft_mysql.conf /opt/server/coreseek/etc
配置 /opt/server/coreseek/etc/csft_mysql.conf 参数 ;注意编码问题;
#源定义 source mysql { type = mysql sql_host = 127.0.0.1 sql_user = root sql_pass = 123456 sql_db = test sql_port = 3306 sql_query_pre = SET NAMES utf8 sql_query = SELECT id, group_id, UNIX_TIMESTAMP(date_added) AS date_added, title, content FROM documents #sql_query第一列id需为整数 #title、content作为字符串/文本字段,被全文索引 sql_attr_uint = group_id #从SQL读取到的值必须为整数 sql_attr_timestamp = date_added #从SQL读取到的值必须为整数,作为时间属性 sql_query_info_pre = SET NAMES utf8 #命令行查询时,设置正确的字符集 sql_query_info = SELECT * FROM documents WHERE id=$id #命令行查询时,从数据库读取原始数据信息 } #index定义 index mysql { source = mysql #对应的source名称 path = /opt/server/coreseek/var/data/mysql #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/... docinfo = extern mlock = 0 morphology = none min_word_len = 1 html_strip = 0 #中文分词配置,详情请查看:http://www.coreseek.cn/products-install/coreseek_mmseg/ charset_dictpath = /opt/server/mmseg/etc/ #BSD、Linux环境下设置,/符号结尾 #charset_dictpath = etc/ #Windows环境下设置,/符号结尾,最好给出绝对路径,例如:C:/usr/local/coreseek/etc/... charset_type = zh_cn.utf-8 } #全局index定义 indexer { mem_limit = 128M } #searchd服务定义 searchd { listen = 9312 read_timeout = 5 max_children = 30 max_matches = 1000 seamless_rotate = 0 preopen_indexes = 0 unlink_old = 1 pid_file = /opt/server/coreseek/var/log/searchd_mysql.pid log = /opt/server/coreseek/var/log/searchd_mysql.log query_log = /opt/server/coreseek/var/log/query_mysql.log }
1.4测试
/opt/server/coreseek/bin/indexer -c /opt/server/coreseek/etc/csft.conf –all
/opt/server/coreseek/bin/search -c /opt/server/coreseek/etc/csft.conf 网络搜索
1.5词库管理
词库文件
/opt/server/mmseg/bin/mmseg -u /opt/server/mmseg/etc/unigram.txt
unigram.txt.uni 更名为 uni.lib 放入对应字典目录
二、sphinx-for-chinese
=======================================================================================================
官网 http://www.sphinx-search.com
1、安装
./configure –prefix=/opt/server/sphinx-for-chinese –with-mysql=/opt/server/mysql
make
make install
2、中文支持
2.1 生成字典
/opt/server/sphinx-for-chinese/bin/mkdict xdict_1.1.txt xdict
2.2 配置使用字典
mv xdict /opt/server/sphinx-for-chinese/etc/xdict

3、启动服务
/opt/server/sphinx/bin/searchd
4、php分词 scws
官网 http://www.ftphp.com/scws/
4.1 安装
./configure –prefix=/opt/server/scws
make
make install
4.2 词库
scws-dict-chs-utf8.tar.bz2 解压放入 /opt/server/scws/etc
词库 dict.utf-8.xdb
规则 rules.utf-8.ini
4.3 php 扩展
源码在 phpext下
/opt/server/php/bin/phpize
./configure –with-scws=/opt/server/scws –with-php-config=/opt/server/php/bin/php-config
make
make install
vi php.ini
[scws]
extension = scws.so
scws.default.charset = utf-8
scws.default.fpath = /opt/server/scws/etc
查看
/opt/server/php/bin/php -m |grep scws
4.4 分词测试
官方测试地址:http://www.ftphp.com/scws/docs.php
详见测试文件 test_all.php
<?php echo ‘<p>‘.microtime(true).‘</p>‘; //搜索词 $key = trim($_GET[‘k‘]); //========================================分词 $so = scws_new(); $so->set_charset(‘utf-8‘); //默认词库 $so->add_dict(ini_get(‘scws.default.fpath‘) . ‘/dict.utf-8.xdb‘); //自定义词库 $so->add_dict(‘./dd.txt‘,SCWS_XDICT_TXT); //默认规则 $so->set_rule(ini_get(‘scws.default.fpath‘) . ‘/rules.utf-8.ini‘); //设定分词返回结果时是否去除一些特殊的标点符号 $so->set_ignore(true); //设定分词返回结果时是否复式分割,如“中国人”返回“中国+人+中国人”三个词。 // 按位异或的 1 | 2 | 4 | 8 分别表示: 短词 | 二元 | 主要单字 | 所有单字 //1,2,4,8 分别对应常量 SCWS_MULTI_SHORT SCWS_MULTI_DUALITY SCWS_MULTI_ZMAIN SCWS_MULTI_ZALL $so->set_multi(false); //设定是否将闲散文字自动以二字分词法聚合 $so->set_duality(false); //设定搜索词 $so->send_text($key); $words_array = $so->get_result(); foreach($words_array as $v) { $words = $words.‘ ‘.$v[‘word‘]; } $so->close(); echo ‘<p>输入:‘.$key.‘</p>‘; echo ‘<p>分词:‘.$words.‘</p>‘; //var_dump($words); //exit; //========================================搜索 require_once ‘sphinxapi.php‘; $sc = new SphinxClient(); $sc->SetServer(‘127.0.0.1‘,9312); $sc->SetMatchMode(SPH_MATCH_ALL); $sc->SetArrayResult(TRUE); $res = $sc->Query($words); var_dump($res); echo ‘<p>‘.microtime(true).‘</p>‘; exit; ?>
其他高阶操作
=======================================================================================================
5 索引
//索引某个索引
/opt/server/sphinx/bin/indexer test1
//searchd 索引某个索引
/opt/server/sphinx/bin/indexer test1 –rotate
//指定索引搜索
/opt/server/sphinx/bin/indexer -i test1 ‘逗她男’
5.1 增量索引方案
//创建表记录偏移
CREATE TABLE search_counter
(
counterid INTEGER PRIMARY KEY NOT NULL,
max_doc_id INTEGER NOT NULL
);
//增量索引
/opt/server/sphinx/bin/indexer test1stemmed –rotate
//合并索引
/opt/server/sphinx/bin/indexer –merge test1 test1stemmed –rotate
索引策略
1、搜索时,同时从主索引和增量索引取数据
2、每5分钟,运行一次增量索引;满足新数据搜索需求
3、每晚,运行一次主索引,同时会更新索引标示;再运行增量索引,实质为清空增量索引,避免与主索引重复
4、好处:避免开合并索引,合并索引效率较差
5、如数据量特别大,可考虑合并索引的方案
索引策略shell
//add.sh
#!/bin/sh

5.2 实时索引
策略:
在插入Myslq数据的同时,将需要索引的数据,同时往sphinx 虚拟Mysql数据库写入一份,实时索引
应用场景:
对实施搜索要求非常要的应用,一般不推荐此方式,尚且不稳定
方案:
编写相关PHP类,在Myslq插入数据的类中,同时插入索引数据,对前端使用者无需关心逻辑
详情配置
