Question

我目前有这个SQL查询：

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

然而，如果它们在EITHER htext或关键字中匹配，我将返回行...我希望关键字必须在htext AND关键字中匹配。我也有问题实际上按照mysql 5.1中的相关性排序

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

必须在布尔模式下匹配两列
