你的桌子是MISAM吗?我在这里做了一个测试,它工作正常。
CREATE TABLE `foo` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`sentence` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
insert into foo values (null, 'get software free');
insert into foo values (null, 'here software download');
mysql> SELECT * FROM `foo` WHERE MATCH(sentence) AGAINST('software' IN BOOLEAN MODE);
+----+------------------------+
| id | sentence |
+----+------------------------+
| 1 | get software free |
| 2 | here software download |
