mysql - 全文搜索返回空结果时出现问题

Question

我在尝试对 mysql 中的表执行全文搜索时遇到问题。相关表具有以下创建命令:

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，其中一列有全文。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('') 

无论 against 子句中包含什么单词，我每次都会得到一个空结果集。我在这里犯了什么愚蠢的错误？

这里的一个例子是我正在测试的一行，它有一个来自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')

或者我知道在那里的任何单词或短语(任何长度，任何单词)......但它仍然返回一个空集。 我知道这一定是我错过的一些简单的东西，但我不知道它可能是什么。

Answer 1

什么话？您知道，有些词不被视为“the”或“how”，这些词通常看起来很有意义。那么单词必须有最小长度。

最后!

In addition, words that are present in 50% or more of the rows are considered common and do not match.

我敢打赌这里就是这种情况。了解更多相关信息here.
