假设我有两列,关键字和内容.我有两个全文索引.我希望关键字中的foo行与内容中的foo行具有更多相关性.我需要做些什么才能使MySQL对关键字中的匹配项进行加权？

我正在使用"匹配"语法.

解:

能够以下列方式完成这项工作:

SELECT *, 
CASE when Keywords like '%watermelon%' then 1 else 0 END as keywordmatch, 
CASE when Content like '%watermelon%' then 1 else 0 END as contentmatch,
MATCH (Title, Keywords, Content) AGAINST ('watermelon') AS relevance 
FROM about_data  
WHERE MATCH(Title, Keywords, Content) AGAINST ('watermelon' IN BOOLEAN MODE) 
HAVING relevance > 0  
ORDER by keywordmatch desc, contentmatch desc, relevance desc
