Question

CREATE TABLE `channels` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(30) DEFAULT NULL,
  `description` text,
  `tagline` varchar(50) DEFAULT NULL,
  `created_at` datetime DEFAULT NULL,
  `image` varchar(50) DEFAULT NULL,
  `user_id` int(10) unsigned NOT NULL,
  PRIMARY KEY (`id`),
  KEY `index_channels_user` (`user_id`),
  FULLTEXT KEY `description` (`description`)
) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;


INSERT INTO 
 `channels` (`id`, `name`, `description`, `tagline`, `created_at`, `image`, `user_id`)
VALUES
 (1, 'sdsd', 'Hello world!', 'dsdsd', '2011-10-09 11:31:59', NULL, 1);


SELECT
  c.id, c.name
FROM channels c
WHERE 
  MATCH(c.description) AGAINST ('Hell' IN BOOLEAN MODE)

Answer 2

您插入的数据不包含“地狱”一词。试试这个：

SELECT
  c.id, c.name
FROM channels c
WHERE 
  MATCH(c.description) AGAINST ('Hell*' IN BOOLEAN MODE)

MySQL匹配不正常工作
