Question

我遇到了尝试在mysql中对表执行全文搜索的问题。有问题的表具有以下create命令：

CREATE TABLE IF NOT EXISTS `resume_contents` 
(`resumeid` int(100) NOT NULL AUTO_INCREMENT,
`jobseekerid` varchar(255) NOT NULL, 
`resumecontents` text, 
PRIMARY KEY (`resumeid`), 
UNIQUE KEY `jobseekerid` (`jobseekerid`), 
FULLTEXT KEY `resumecontents` (`resumecontents`) ) 
ENGINE=MyISAM  DEFAULT CHARSET=latin1 ;

所以基本上只有3列，只有一列的全文。然后，当我尝试使用以下命令进行全文搜索时：

SELECT *  FROM `resume_contents` WHERE MATCH (resumecontents) AGAINST('')

每次都得到一个空结果集，无论反对子句中有什么单词。我在这里犯了什么愚蠢的错误？

作为一个例子，我正在测试一行，它有来自resume.com的简历样本。

INSERT INTO `resume_contents` (`resumeid`, `jobseekerid`, `resumecontents`) VALUES (2, '14', 'Objectives\nI am looking for a position at This Company where I can maximize my programming skills, project management, leadership skills, and create new and exciting tools.\n\n\nSummary\nI have had 3 years experience in web design and development.

然后我搜索：

SELECT * FROM `resume_contents` WHERE MATCH(`resumecontents`) AGAINST ('Company')

或者我知道的任何单词或短语（任何长度，任何单词）都在那里......然而它仍然会返回一个空集。我知道它一定是简单的我想念但我不知道它会是什么。

Answer 1

用什么词？你知道，某些词语不被视为“the”或“how”，这些词语似乎经常是有意义的。然后单词必须具有最小长度。

最后！

此外，50％或更多行中出现的单词被认为是常见的并且不匹配。

我打赌这就是这种情况。详细了解here.
