Sphinx在windows下安装使用[支持中文全文检索]
一、关于Sphinx
Sphinx 是一个在GPLv2 下发布的一个全文检索引擎,商业授权(例如, 嵌入到其他程序中)需要联系作者(Sphinxsearch.com)以获得商业授权。
一般而言,Sphinx是一个独立的搜索引擎,意图为其他应用提供高速、低空间占用、高结果相关度的全文搜索功能。Sphinx可以非常容易的与 SQL数据库和脚本语言集成。
当前系统内置MySQL和PostgreSQL 数据库数据源的支持,也支持从标准输入读取特定格式的XML数据。通过修改源代码,用户可以自行增加新的数据源(例如:其他类型的DBMS的原生支持)。
?
搜索API支持PHP、Python、Perl、Rudy和Java,并且也可以用作MySQL存储引擎。搜索API非常简单,可以在若干个小时之 内移植到新的语言上。
Sphinx特性:
高速的建立索引(在当代CPU上,峰值性能可达到10MB/秒);高性能的搜索(在24GB的文本数据上,平均每次检索响应时间小于0.1秒);可处理海量数据(目前已知可以处理超过100GB的文本数据,在单一CPU的系统上可处理100M文档);提供了优秀的相关度算法,基于短语相似度和统计(BM25)的复合Ranking方法;支持分布式搜索;
提供文件的摘录生成;可作为MySQL的存储引擎提供搜索服务;支持布尔、短语、词语相似度等多种检索模式;文档支持多个全文检索字段(最大不超过32个);文档支持多个额外的属性信息(例如:分组信息,时间戳等);停止词查询;支持单一字节编码和UTF-8编码;原生的MySQL支持(同时支持MyISAM和InnoDB);原生的PostgreSQL支持.中文手册可以在这里获得(酷勤 网备用下载地址:sphinx_doc_zhcn_0.9.pdf)。

二、Sphinx在windows上的安装
1.直接在http://www.sphinxsearch.com/downloads.html找到最新的windows版本,我这里下的是Win32 release binaries with MySQL support,下载后解压在D:\sphinx目录下;
2.在D:\sphinx\下新建一个data目录用来存放索引文件,一个log目录方日志文件,复制D:\sphinx\sphinx.conf.in到D:\sphinx\bin\sphinx.conf(注意修改文件名);
3.修改D:\sphinx\bin\sphinx.conf,我这里列出需要修改的几个:
??? type??????? = mysql # 数据源,我这里是mysql
??? sql_host??? = localhost # 数据库服务器
??? sql_user??? = root # 数据库用户名
??? sql_pass??? = '' # 数据库密码
??? sql_db????? = test # 数据库
??? sql_port??? = 3306 # 数据库端口
??? sql_query_pre?? = SET NAMES utf8 # 去掉此行前面的注释,如果你的数据库是uft8编码的
??? index test1
??? {
??? # 放索引的目录
???? path?? = D:/sphinx/data/
??? # 编码
???? charset_type? = utf-8
???? #? 指定utf-8的编码表
???? charset_table? = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F
???? # 简单分词,只支持0和1,如果要搜索中文,请指定为1
???? ngram_len??? = 1
??? # 需要分词的字符,如果要搜索中文,去掉前面的注释
???? ngram_chars?? = U+3000..U+2FA1F
??? }
??? # index test1stemmed : test1
??? # {
???? # path?? = @CONFDIR@/data/test1stemmed
???? # morphology? = stem_en
??? # }
??? # 如果没有分布式索引,注释掉下面的内容
??? # index dist1
??? # {
???? # 'distributed' index type MUST be specified
???? # type??? = distributed
???? # local index to be searched
???? # there can be many local indexes configured
???? # local??? = test1
???? # local??? = test1stemmed
???? # remote agent
???? # multiple remote agents may be specified
???? # syntax is 'hostname:port:index1,[index2[,...]]
???? # agent??? = localhost:3313:remote1
???? # agent??? = localhost:3314:remote2,remote3
???? # remote agent connection timeout, milliseconds
???? # optional, default is 1000 ms, ie. 1 sec
???? # agent_connect_timeout = 1000
???? # remote agent query timeout, milliseconds
???? # optional, default is 3000 ms, ie. 3 sec
???? # agent_query_timeout? = 3000
??? # }
??? # 搜索服务需要修改的部分
??? searchd
??? {
???? # 日志
???? log???? = D:/sphinx/log/searchd.log
???? # PID file, searchd process ID file name
???? pid_file?? = D:/sphinx/log/searchd.pid
???? # windows下启动searchd服务一定要注释掉这个
???? # seamless_rotate? = 1
??? }
4.导入测试数据
C:\Program Files\MySQL\MySQL Server 5.0\bin>mysql -uroot test<d:/sphinx/example.sql
5.建立索引
??? D:\sphinx\bin>indexer.exe all
??? Sphinx 0.9.8-release (r1533)
??? Copyright (c) 2001-2008, Andrew Aksyonoff
??? using config file ‘./sphinx.conf’…
??? indexing index ‘test1′…
??? collected 4 docs, 0.0 MB
??? sorted 0.0 Mhits, 100.0% done
??? total 4 docs, 193 bytes
??? total 0.101 sec, 1916.30 bytes/sec, 39.72 docs/sec
??? D:\sphinx\bin>
6.搜索’test’试试
??? D:\sphinx\bin>search.exe test
??? Sphinx 0.9.8-release (r1533)
??? Copyright (c) 2001-2008, Andrew Aksyonoff
??? using config file ‘./sphinx.conf’…
??? index ‘test1′: query ‘test ‘: returned 3 matches of 3 total in 0.000 sec
??? displaying matches:
??? 1. document=1, weight=2, group_id=1, date_added=Wed Nov 26 14:58:59 2008
??????????? id=1
??????????? group_id=1
??????????? group_id2=5
??????????? date_added=2008-11-26 14:58:59
??????????? title=test one
??????????? content=this is my test document number one. also checking search within
???? phrases.
??? 2. document=2, weight=2, group_id=1, date_added=Wed Nov 26 14:58:59 2008
??????????? id=2
??????????? group_id=1
??????????? group_id2=6
??????????? date_added=2008-11-26 14:58:59
??????????? title=test two
??????????? content=this is my test document number two
??? 3. document=4, weight=1, group_id=2, date_added=Wed Nov 26 14:58:59 2008
??????????? id=4
??????????? group_id=2
??????????? group_id2=8
??????????? date_added=2008-11-26 14:58:59
??????????? title=doc number four
??????????? content=this is to test groups
??? words:
??? 1. ‘test’: 3 documents, 5 hits
??? D:\sphinx\bin>
都所出来了吧。
6.测试中文搜索
修改test数据库中documents数据表,
??? UPDATE `test`.`documents` SET `title` = ‘测试中文’, `content` = ‘this is my test document number two,应该搜的到吧’ WHERE `documents`.`id` = 2;
重建索引:
D:\sphinx\bin>indexer.exe all
搜索’中文’试试:
??? D:\sphinx\bin>search.exe 中文
??? Sphinx 0.9.8-release (r1533)
??? Copyright (c) 2001-2008, Andrew Aksyonoff
??? using config file ‘./sphinx.conf’…
??? index ‘test1′: query ‘中文 ‘: returned 0 matches of 0 total in 0.000 sec
??? words:
??? D:\sphinx\bin>
貌似没有搜到,这是因为windows命令行中的编码是gbk,当然搜不出来。我们可以用程序试试,在D:\sphinx\api下新建一个foo.php的文件,注意utf-8编码
??? <?php
??? require ’sphinxapi.php’;
??? $s = new SphinxClient();
??? $s->SetServer(’localhost’,3312);
??? $result = $s->Query(’中文’);
??? var_dump($result);
??? ?>
启动Sphinx searchd服务
??? D:\sphinx\bin>searchd.exe
??? Sphinx 0.9.8-release (r1533)
??? Copyright (c) 2001-2008, Andrew Aksyonoff
??? WARNING: forcing console mode on Windows
??? using config file ‘./sphinx.conf’…
??? creating server socket on 0.0.0.0:3312
??? accepting connections
执行PHP查询:
??? php d:/sphinx/api/foo.php
