TABLE `T` ( .... FULLTEXT KEY `title_fc` (`titleindex`), FULLTEXT KEY `shortname_fc` (`shortnameindex`) ) ENGINE=InnoDB AUTO_INCREMENT=50962041 DEFAULT CHARSET=utf8

创建了两个全文索引，但是在查找的时候，却出现如下这样的错误。

mysql> SELECT count(1) as count FROM T a WHERE 1 = 1 AND MATCH (a.titleindex) AGAINST (‘"5YeM 5Yqo"‘ IN BOOLEAN MODE );
+-------+
| count |
+-------+
| 70 |
+-------+
1 row in set (0.01 sec)

mysql> SELECT count(1) as count FROM T a WHERE 1 = 1 AND MATCH (a.shortnameindex) AGAINST (‘"5YeM 5Yqo"‘ IN BOOLEAN MODE ) ;
+-------+
| count |
+-------+
| 6 |
+-------+
1 row in set (0.00 sec)

mysql> SELECT count(1) as count FROM T a WHERE 1 = 1 AND MATCH (a.shortnameindex ,a.titleindex) AGAINST (‘"5YeM 5Yqo"‘ IN BOOLEAN MODE ) ;
ERROR 1191 (HY000): Can‘t find FULLTEXT index matching the column list

单独match某一列可以正常查询，但是match多列就报错。

后来从MySQL的文档上面找到：The MATCH() column list must match exactly the column list in some FULLTEXT index definition for the table, unless this MATCH() is IN BOOLEAN MODE on a MyISAM table.

【mysql】全文索引match多列报错

目前，MySQL全文检索不支持中文和日文。追问我可以确定目前 MySQL全文检索支持中文和日文。
