  • PHP基于Sphinx+Swcs中文分词的全文的检索

    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
    {
    	type			= mysql
    	sql_host		= localhost
    	sql_user		= root
    	sql_pass		= 123456

    	sql_query_pre = SET NAMES utf8  
            sql_query_pre = SET SESSION query_cache_type=OFF  
            sql_query = 
    	SELECT a.id, a.userid,b.username, UNIX_TIMESTAMP(a.addtime) AS addtime, a.post, a.summary 
    	FROM userinfo a left join users b on a.userid = b.id  
    	sql_attr_uint = userid  
    	sql_field_string = username  
    	sql_field_string = post  
    	sql_attr_timestamp = addtime
    	sql_attr_uint		= group_id
    	sql_attr_timestamp	= date_added
    	sql_ranged_throttle	= 0
    }
    source src1throttled : users 
    {

    }
    indexer
    {

    }
    searchd

    	max_batch_queries	= 32
    	workers			= threads # for RT to work
    }
    index users 
    {  
    	source = users 
    	path = /usr/local/sphinx/var/data/users 
    	docinfo = extern  
    	mlock = 0  
    	morphology = none  
    	min_word_len = 1

    	charset_table = U+FF10..U+FF19->0..9, 0..9, U+FF41..U+FF5A->a..z, U+FF21..U+FF3A->a..z,A..Z->a..z, a..z, U+0149, U+017F, U+0138, U+00DF, U+00FF, U+00C0..U+00D6->U+00E0..U+00F6,U+00E0..U+00F6, U+00D8..U+00DE->U+00F8..U+00FE, U+00F8..U+00FE, U+0100->U+0101, U+0101,U+0102->U+0103, U+0103, U+0104->U+0105, U+0105, U+0106->U+0107, U+0107, U+0108->U+0109,U+0109, U+010A->U+010B, U+010B, U+010C->U+010D, U+010D, U+010E->U+010F, U+010F,U+0110->U+0111, U+0111, U+0112->U+0113, U+0113, U+0114->U+0115, U+0115, U+0116->U+0117,U+0117, U+0118->U+0119, U+0119, U+011A->U+011B, U+011B, U+011C->U+011D, U+011D,U+011E->U+011F, U+011F, U+0130->U+0131, U+0131, U+0132->U+0133, U+0133, U+0134->U+0135,U+0135, U+0136->U+0137, U+0137, U+0139->U+013A, U+013A, U+013B->U+013C, U+013C,U+013D->U+013E, U+013E, U+013F->U+0140, U+0140, U+0141->U+0142, U+0142, U+0143->U+0144,U+0144, U+0145->U+0146, U+0146, U+0147->U+0148, U+0148, U+014A->U+014B, U+014B,U+014C->U+014D, U+014D, U+014E->U+014F, U+014F, U+0150->U+0151, U+0151, U+0152->U+0153,U+0153, U+0154->U+0155, U+0155, U+0156->U+0157, U+0157, U+0158->U+0159, U+0159,U+015A->U+015B, U+015B, U+015C->U+015D, U+015D, U+015E->U+015F, U+015F, U+0160->U+0161,U+0161, U+0162->U+0163, U+0163, U+0164->U+0165, U+0165, U+0166->U+0167, U+0167,U+0168->U+0169, U+0169, U+016A->U+016B, U+016B, U+016C->U+016D, U+016D, U+016E->U+016F,U+016F, U+0170->U+0171, U+0171, U+0172->U+0173, U+0173, U+0174->U+0175, U+0175,U+0176->U+0177, U+0177, U+0178->U+00FF, U+00FF, U+0179->U+017A, U+017A, U+017B->U+017C,U+017C, U+017D->U+017E, U+017E, U+0410..U+042F->U+0430..U+044F, U+0430..U+044F,U+05D0..U+05EA, U+0531..U+0556->U+0561..U+0586, U+0561..U+0587, U+0621..U+063A, U+01B9,U+01BF, U+0640..U+064A, U+0660..U+0669, U+066E, U+066F, U+0671..U+06D3, U+06F0..U+06FF,U+0904..U+0939, U+0958..U+095F, U+0960..U+0963, U+0966..U+096F, U+097B..U+097F,U+0985..U+09B9, U+09CE, U+09DC..U+09E3, U+09E6..U+09EF, U+0A05..U+0A39, U+0A59..U+0A5E,U+0A66..U+0A6F, U+0A85..U+0AB9, U+0AE0..U+0AE3, U+0AE6..U+0AEF, U+0B05..U+0B39,U+0B5C..U+0B61, U+0B66..U+0B6F, U+0B71, U+0B85..U+0BB9, U+0BE6..U+0BF2, U+0C05..U+0C39,U+0C66..U+0C6F, U+0C85..U+0CB9, U+0CDE..U+0CE3, U+0CE6..U+0CEF, U+0D05..U+0D39, U+0D60,U+0D61, U+0D66..U+0D6F, U+0D85..U+0DC6, U+1900..U+1938, U+1946..U+194F, U+A800..U+A805,U+A807..U+A822, U+0386->U+03B1, U+03AC->U+03B1, U+0388->U+03B5, U+03AD->U+03B5,U+0389->U+03B7, U+03AE->U+03B7, U+038A->U+03B9, U+0390->U+03B9, U+03AA->U+03B9,U+03AF->U+03B9, U+03CA->U+03B9, U+038C->U+03BF, U+03CC->U+03BF, U+038E->U+03C5,U+03AB->U+03C5, U+03B0->U+03C5, U+03CB->U+03C5, U+03CD->U+03C5, U+038F->U+03C9,U+03CE->U+03C9, U+03C2->U+03C3, U+0391..U+03A1->U+03B1..U+03C1,U+03A3..U+03A9->U+03C3..U+03C9, U+03B1..U+03C1, U+03C3..U+03C9, U+0E01..U+0E2E,U+0E30..U+0E3A, U+0E40..U+0E45, U+0E47, U+0E50..U+0E59, U+A000..U+A48F, U+4E00..U+9FBF,U+3400..U+4DBF, U+20000..U+2A6DF, U+F900..U+FAFF, U+2F800..U+2FA1F, U+2E80..U+2EFF,U+2F00..U+2FDF, U+3100..U+312F, U+31A0..U+31BF, U+3040..U+309F, U+30A0..U+30FF,U+31F0..U+31FF, U+AC00..U+D7AF, U+1100..U+11FF, U+3130..U+318F, U+A000..U+A48F,U+A490..U+A4CF  
    	ngram_len = 1  
    	ngram_chars = U+4E00..U+9FBF, U+3400..U+4DBF, U+20000..U+2A6DF, U+F900..U+FAFF,U+2F800..U+2FA1F, U+2E80..U+2EFF, U+2F00..U+2FDF, U+3100..U+312F, U+31A0..U+31BF,U+3040..U+309F, U+30A0..U+30FF,U+31F0..U+31FF, U+AC00..U+D7AF, U+1100..U+11FF,U+3130..U+318F, U+A000..U+A48F, U+A490..U+A4CF  
    }
    common
    {
    }
    

    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);
