Sphinx 之 Coreseek、Sphinx-for-chinaese、Sphinx+Scws 评测

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

    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

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
/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

详情配置

/opt/server/sphinx/etc/sphinx.conf

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
