必須在布爾模式

Question

我有這個目前SQL查詢兩列匹配：

SELECT htext FROM paragraphs WHERE MATCH(htext, keywords) 
AGAINST('+genomics' IN BOOLEAN MODE) ORDER BY MATCH(htext) 
AGAINST('+genomics' IN BOOLEAN MODE)desc 

但是我找回行，如果他們匹配任何一種htext或關鍵字...我想關鍵字必須匹配在htext和關鍵字中。我也有問題，實際上按照相關性在MySQL 5.1中排序5.1

Answer 1

SELECT htext, MATCH(htext) AGAINST('+genomics' IN BOOLEAN MODE) AS Relevance FROM paragraphs 
WHERE MATCH(htext) AGAINST('+genomics' IN BOOLEAN MODE) 
AND MATCH(keywords) AGAINST('+genomics' IN BOOLEAN MODE) 
ORDER BY Relevance DESC
