一.安装配置 安装参见： http://www.ttlsa.com/html/1236.html 配置如下： # vi sphinx.conf # source块设置数据源
source src1 { type = mysql sql_host = localhost sql_user = root sql_pass = sql_db = sphinx sql_port = 3306 # optional, default is 3306 sql_query = \ SELECT id, group_id, UNIX_TIMESTAMP(date_added) AS date_added, title, content \ FROM documents sql_attr_uint = group_id sql_attr_timestamp = date_added sql_query_info = SELECT * FROM documents WHERE id=$id }
# index块设置索引保存目录等
index test1 { source = src1 path = /data/sphinx/ docinfo = extern charset_type = sbcs }
# indexer块设置索引选项，比如内存限制大小
indexer { mem_limit = 32M }
# searchd块设置搜索索引时使用的选项
searchd { port = 9312 log = /var/log/searchd.log query_log = /var/log/query.log read_timeout = 5 max_children = 30 pid_file = /var/log/searchd.pid max_matches = 1000 seamless_rotate = 1 preopen_indexes = 0 unlink_old = 1 }
二.新建相关表
mysql> CREATE TABLE documents -> ( -> id INTEGER PRIMARY KEY NOT NULL AUTO_INCREMENT, -> group_id INTEGER NOT NULL, -> group_id2 INTEGER NOT NULL, -> date_added DATETIME NOT NULL, -> title VARCHAR(255) NOT NULL, -> content TEXT NOT NULL -> ); Query OK, 0 rows affected (0.00 sec)
mysql> REPLACE INTO documents ( id, group_id, group_id2, date_added, title, content ) VALUES -> ( 1, 1, 5, NOW(), 'test one', 'this is my test document number one. also checking search within phrases.' ), -> ( 2, 1, 6, NOW(), 'test two', 'this is my test document number two' ), -> ( 3, 2, 7, NOW(), 'another doc', 'this is another group' ), -> ( 4, 2, 8, NOW(), 'doc number four', 'this is to test groups' ); Query OK, 4 rows affected (0.02 sec) Records: 4 Duplicates: 0 Warnings: 0
mysql> CREATE TABLE tags -> ( -> docid INTEGER NOT NULL, -> tagid INTEGER NOT NULL, -> UNIQUE(docid,tagid) -> ); Query OK, 0 rows affected (0.01 sec)
mysql> INSERT INTO tags VALUES -> (1,1), (1,3), (1,5), (1,7), -> (2,6), (2,4), (2,2), -> (3,15), -> (4,7), (4,40); Query OK, 10 rows affected (0.02 sec) Records: 10 Duplicates: 0 Warnings: 0
<?php require_once "sphinxapi.php"; $search = new SphinxClient; $search->setServer("localhost", 9312); $search->setMatchMode(SPH_MATCH_ANY); $search->SetArrayResult ( true ); $search->setMaxQueryTime(3); print_r($search->query("test")); //"test"为要搜索的词 ?>
结果如下：
Array ( [error] => [warning] => [status] => 0 [fields] => Array ( [0] => title [1] => content ) [attrs] => Array ( [group_id] => 1 [date_added] => 2 ) [matches] => Array //匹配的结果 ( [0] => Array ( [id] => 1 [weight] => 2 [attrs] => Array ( [group_id] => 1 [date_added] => 1339747121 ) ) [1] => Array ( [id] => 2 [weight] => 2 [attrs] => Array ( [group_id] => 1 [date_added] => 1339747121 ) ) [2] => Array ( [id] => 4 [weight] => 1 [attrs] => Array ( [group_id] => 2 [date_added] => 1339747121 ) ) ) [total] => 3 [total_found] => 3 [time] => 0.000 [words] => Array ( [test] => Array ( [docs] => 3 [hits] => 5 ) ) )
说明: [docs] => 3有三条结果想匹配,[hits] => 5命中5次,与数据库相对应的id是1,2,4.耗时[time] => 0.000 查询数据库结果如下： mysql> select *, (select unix_timestamp(date_added)) as ut from documents where id in (1,2,4); +----+----------+-----------+---------------------+-----------------+---------------------------------------------------------------------------+------------+ | id | group_id | group_id2 | date_added | title | content | ut | +----+----------+-----------+---------------------+-----------------+---------------------------------------------------------------------------+------------+ | 1 | 1 | 5 | 2012-06-15 15:58:41 | test one | this is my test document number one. also checking search within phrases. | 1339747121 | | 2 | 1 | 6 | 2012-06-15 15:58:41 | test two | this is my test document number two | 1339747121 | | 4 | 2 | 8 | 2012-06-15 15:58:41 | doc number four | this is to test groups | 1339747121 | +----+----------+-----------+---------------------+-----------------+---------------------------------------------------------------------------+------------+ 3 rows in set (0.00 sec) 因此对于大量数据，为了提高查询速度，可以先通过sphinx查找出id，再通过id来查询数据库数据。 如需转载请注明出处：http://www.ttlsa.com/html/1346.html
