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
