MySQL匹配不正常

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) 

我得到0個結果，爲什麼？

Answer 1

燁@Ben有一個點那裏，禁用詞造成這個問題

嘗試http://bugs.mysql.com/bug.php?id=19583

這些替代固定閱讀這些

全文布爾模式搜索停用詞問題問題在http://www.nivas.hr/blog/2009/09/15/how-to-disable-mysql-fulltext-stopwords/

Answer 2

您插入的數據中不包含「地獄」一詞。 試試這個：

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