I'm really stumped on this MySQL problem

If you create a test table like this:

CREATE TABLE `names` (
  `id` int(10) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=6 DEFAULT CHARSET=latin1;

insert  into `names`(`id`,`name`) values (1,'Joseph');
insert  into `names`(`id`,`name`) values (2,'Dick');
insert  into `names`(`id`,`name`) values (3,'Rather');
insert  into `names`(`id`,`name`) values (4,'Steven');
insert  into `names`(`id`,`name`) values (5,'Anna');

And perform this search:

SELECT * FROM `names` WHERE MATCH(NAME) AGAINST ('+rather* ' IN BOOLEAN MODE);

You will see that there are no results. However substituting 'rather' for any of the other names in the tabl开发者_如何学JAVAe works fine... What's wrong with 'Rather'???

It's mysql version 5.5.8.

Any help greatly appreciated... I really have no idea on this one!!

Thanks.


rather is a MySQL stopword. You cannot full text search for it by default.

To work around that, you can disable stopwords by setting the ft_stopword_file system variable to the empty string.


'Rather' is the stopword for full text search in BOOLEAN mode for MySql

for more details you can see the following links http://dev.mysql.com/doc/refman/5.5/en/fulltext-boolean.html http://dev.mysql.com/doc/refman/5.5/en/fulltext-stopwords.html


apparently you didnt create fulltext index

check this:
