记得以前sphinx是不支持联合查询的，第一次接触sphinx，好像2010年初的时候，当时写过一篇关于sphinx安装的文章。 sphinx mmseg mysql 中文分词 ，下面举例说明，sphinx的联合查询用法。 一，添加二张测试表和数据 1,users表和数据 mysql desc users;+------

记得以前sphinx是不支持联合查询的，第一次接触sphinx，好像2010年初的时候，当时写过一篇关于sphinx安装的文章。sphinx mmseg mysql 中文分词，下面举例说明，sphinx的联合查询用法。

一，添加二张测试表和数据

1,users表和数据

mysql> desc users;
+----------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+----------+-------------+------+-----+---------+----------------+
| user_id | int(11) | NO | PRI | NULL | auto_increment |
| username | varchar(20) | NO | | NULL | |
+----------+-------------+------+-----+---------+----------------+
2 rows in set (0.00 sec)
mysql> select * from users;
+------------+------------+
| user_id | username |
+------------+------------+
| 1311895262 | 张三 |
| 1311895263 | tank张二 |
| 1311895264 | tank张一 |
| 1311895265 | tank张 |
+------------+------------+
4 rows in set (0.00 sec)

?2,orders表和数据

mysql> desc orders;
+--------------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+--------------+-------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| user_id | int(11) | NO | | NULL | |
| create_time | datetime | NO | | NULL | |
| product_name | varchar(20) | NO | | NULL | |
| summary | text | NO | | NULL | |
+--------------+-------------+------+-----+---------+----------------+
5 rows in set (0.00 sec)
mysql> select * from orders;
+----+------------+---------------------+----------------+--------------+
| id | user_id | create_time | product_name | summary |
+----+------------+---------------------+----------------+--------------+
| 9 | 1311895262 | 2014-08-01 00:24:54 | tank is 坦克 | 技术总监 |
| 10 | 1311895263 | 2014-08-01 00:24:54 | tank is 坦克 | 技术经理 |
| 11 | 1311895264 | 2014-08-01 00:24:54 | tank is 坦克 | DNB经理 |
| 12 | 1311895265 | 2014-08-01 00:24:54 | tank is 坦克 | 运维总监 |
+----+------------+---------------------+----------------+--------------+
4 rows in set (0.00 sec)

二，配置sphinx.conf

source order
{
 type = mysql
 sql_host = localhost
 sql_user = root
 sql_pass =
 sql_db = test
 sql_query_pre = SET NAMES utf8
 sql_query = \
 SELECT a.id, a.user_id,b.username, UNIX_TIMESTAMP(a.create_time) AS create_time, a.product_name, a.summary \
 FROM orders a left join users b on a.user_id = b.user_id
 sql_attr_uint = user_id
 sql_field_string = username
 sql_field_string = product_name
 sql_attr_timestamp = create_time
 sql_ranged_throttle = 0
 sql_query_info = SELECT * FROM orders WHERE id=$id
}
index myorder
{
 source = order
 path = /usr/local/sphinx/var/data/myorder
 docinfo = extern
 mlock = 0
 morphology = none
 min_word_len = 1
 charset_dictpath = /usr/local/mmseg3/etc/
 charset_type = zh_cn.utf-8
 ngram_len = 0
 html_strip = 0
}

注意：在这里a.user_id = b.user_id，等号二边一定要有空格，不然就会报错。

三，重启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

四，测试sphinx

[root@localhost etc]# mysql -h 127.0.0.1 -P 9306                     //登录sphinx,9306端口，不是真实的mysql

+------+--------+------------+------------+-------------+----------------+
4 rows in set (0.01 sec)
mysql> select * from myorder where match('张三');
+------+--------+------------+----------+-------------+----------------+

| 9 | 2500 | 1311895262 | 张三 | 1406823894 | tank is 坦克 |
+------+--------+------------+----------+-------------+----------------+
1 row in set (0.00 sec)
