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

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_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

        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

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

配置 sphinx.conf 参数

加入  
charset\_type = utf-8  
chinese\_dictionary = /opt/server/sphinx-for-chinese/etc/xdict

相关配置详见 /opt/server/sphinx-for-chinese/etc/sphinx.conf；注意编码问题；

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

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  
/opt/server/sphinx/bin/indexer test1stemmed –rotate >> /opt/server/sphinx/var/log/add.sh.log

//all.sh  
\#!/bin/sh  
/opt/server/sphinx/bin/indexer test1 –rotate >> /opt/server/sphinx/var/log/all.sh.log  
/opt/server/sphinx/bin/indexer test1stemmed –rotate >> /opt/server/sphinx/var/log/add.sh.log

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

5.3 多个表独立索引方案

场景：如有用户搜索、商品搜索等多个索引需求

策略：

配置一个多索引方案，每个表单独建立索引

前端根据不同类型选择不同的查询索引；全部，即选择所有索引
