sphinx主索引，增量索引建立

相關命令及步驟

建立主索引： /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft.conf --all 建立增量索引： 1. 建立測試資料表以及資料 2. 修改配置檔案主索引源: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. 建立/更新主索引 4. 建立/更新增量索引 /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft.conf delta 5.重啟索引程序 /usr/local/coreseek/bin/searchd --stop /usr/local/coreseek/bin/searchd -c /usr/local/coreseek/etc/csft.conf 索引合併

/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft.conf --merge main delta --rotate

csft.conf 配置檔案 source src1 index test1 source delta : src1 index delta : test1

建立mysql測試資料表及資料

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');
// 實現增量索引時使用的計數表
create
table sph_counter( counter_id integer
primary
keynot
null,max_doc_id integer
notnull);

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) 
// 獲取結果id集
$ids = array();
foreach($result['matches'] as
$key => $val)
print_r($ids);
// 連線資料庫
$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();
// 搜尋結果高亮顯示
$rule = array(
"before_match" => "",
"after_match" => ""
);foreach ($data
as$key=>$val) 
print_r($data);

新增新分詞

1. 複製unigram.txt檔案為unigram_new.txt 2. 在unigram_new.txt中新增新詞 3. 生成新的詞典檔案：/usr/local/mmseg3/bin/mmseg -u /usr/local/mmseg3/etc/unigram_new.txt 4. 替換原有的uni.lib檔案

5. 重建索引 && 重啟索引
