sphinx安装

相关命令及步骤
    创建主索引：
        /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft.conf --all
    创建增量索引：
        1. 创建测试数据表以及数据
        2. 修改配置文件
            主索引源:sql_query_pre
            增量索引源:sql_query_pre  sql_query  sql_query_post
            主索引:source path
            增量索引:source path
        3. 创建/更新主索引
        4. 创建/更新增量索引
        /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft.conf delta
    重启索引进程
        /usr/local/coreseek/bin/searchd --stop
        /usr/local/coreseek/bin/searchd -c /usr/local/coreseek/etc/csft.conf
    索引合并
        /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft.conf --merge main delta --rotate

创建mysql测试数据表及数据
    CREATE TABLE `documents` (`id` int(11) NOT NULL auto_increment,`group_id` int(11) NOT NULL,`group_id2` int(11) NOT NULL,`date_added` datetime NOT NULL,`title` varchar(255) NOT NULL,`content` text NOT NULL,PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=5;

    INSERT INTO `documents` VALUES ('1', '1', '5', '2008-09-13 21:37:47', 'test one', 'this is my test document number one. also checking search within phrases.');INSERT INTO `documents` VALUES ('2', '1', '6', '2008-09-13 21:37:47', 'test two', 'this is my test document number two');INSERT INTO `documents` VALUES ('3', '2', '7', '2008-09-13 21:37:47', 'another doc', 'this is another group');INSERT INTO `documents` VALUES ('4', '2', '8', '2008-09-13 21:37:47', 'doc number four', 'this is to test groups');

    // 实现增量索引时使用的计数表
    CREATE TABLE sph_counter( counter_id INTEGER PRIMARY KEY NOT NULL, max_doc_id INTEGER NOT NULL);



PHP使用

    <?php

    header("Content-type: text/html; charset=utf-8");

    require_once('sphinxapi.php');

    $s = new SphinxClient();

    $s->setServer("127.0.0.1", 9312);
    $s->setArrayResult(true);
    $s->setMatchMode(SPH_MATCH_ALL);

    $keyword = 'test';

    $result = $s->Query($keyword, '*');
    if ($result['total'] == 0) {
        echo '无搜索结果';die;
    }

    // 获取结果id集
    $ids = array();
    foreach($result['matches'] as $key => $val)
    {
        $ids[] = $val['id'];
    }
    print_r($ids);

    // 连接数据库
    $dsn = "mysql:host=localhost;dbname=test;charset=utf8";
    $db = new PDO($dsn, 'root', '');

    $sql = 'select * from documents where id in('.implode(',', $ids).')';
    $result = $db->query($sql);
    $result->setFetchMode(PDO::FETCH_ASSOC);

    $data = $result->fetchAll();

    // 搜索结果高亮显示
    $rule = array(
                "before_match" => "<font style='font-weight:bold;color:#f00'>",
                "after_match" => "</font>"
            );
    foreach ($data as $key=>$val) {
        $data[$key] = $s->BuildExcerpts($val, 'delta', $keyword, $rule);
    }

    print_r($data);



添加新分词
    1. 复制unigram.txt文件为unigram_new.txt
    2. 在unigram_new.txt中添加新词
    3. 生成新的词典文件：/usr/local/mmseg3/bin/mmseg -u /usr/local/mmseg3/etc/unigram_new.txt
    4. 替换原有的uni.lib文件
    5. 重建索引 && 重启索引
