mysql全文搜索问题

Question

嘿,有一个小问题,我不太了解MYSQL全文搜索.我有这个:

 $data = mysql_query("SELECT * FROM posts WHERE MATCH (article) AGAINST ('news')"); 

 while($result = mysql_fetch_array( $data )) 
 { 
 echo $result['title']; 
 echo "<br><br> "; 
 echo $result['article']; 
 echo "<br><br>"; 
 } 

 $anymatches=mysql_num_rows($data); 
 if ($anymatches == 0) 
 { 
 echo "Sorry, but we can not find an entry to match your query<br><br>"; 
 } 

 echo "<b>Searched For:</b> " .$search_term; 

这很好用.它从数据库中提取标题和文章,并回显出数据库中每个项目的所有信息.只从'文章'columnthough中提取信息.....(如果"新闻"只在标题中,它将不会显示在结果中.)反之亦然.如果我查询MATCH(标题),它只会在标题中找到具有给定搜索词的帖子,而不是文章

但是,当我改变MATCH条款时:MATCH(标题,文章),我得到零结果.基本上,我只在一个专栏中遇到了MATCH.

这是posts表的表格模式:(这是来自导出)

CREATE TA BLE帖子(
idint(55)unsigned NOT NULL auto_increment,
titlevarchar(255)collat​​e latin1_german2_ci default NULL,
articletext collat​​e latin1_german2_ci,
post_typevarchar(255)collat​​e latin1_german2_ci default NULL,
daytext collat​​e latin1_german2_ci,
uservarchar(55)collat​​e latin1_german2_ci default NULL,
monthtext collat​​e latin1_german2_ci,
yearint(4)默认为NULL,
member_idint(55)默认为NULL,
publishedtinyint(1)NOT NULL默认为'0',
drafttinyint(1)默认为'0',
slugvarchar(255)collat​​e latin1_german2_ci默认为NULL,
event_monthvarchar(255)自动分页latin1_german2_ci默认为NULL,
event_day1int(2)默认为NULL,
event_day2int(2)默认为NULL,
PRIMARY KEY(id),
FULLTEXT KEY title(title),
FULLTEXT KEY article(article)
)ENGINE = MyISAM;

任何人都知道为什么它不喜欢第二列看？

在两个字段上定义全文索引:

FULLTEXT KEY title_article_fx (title, article)
