按全文匹配最多匹配

Question

我使用以下查询来搜索表中的记录：

SELECT * FROM posts WHERE MATCH (title) AGAINST ('$q')   LIMIT 15

它返回前15个结果，如何按最大匹配数量的顺序对其进行排序？

Answer 1

SELECT *, MATCH (title) AGAINST ('$q') AS mat 
  FROM posts 
  WHERE MATCH (title) AGAINST ('$q') ORDER BY mat LIMIT 15
  ORDER BY mat DESC

您可以添加ORDER BY mat DESC 或 ORDER BY mat

来添加升序或降序

Answer 2

试试这个

SELECT *,MATCH (title) AGAINST ('$q') AS relevance FROM posts WHERE MATCH (title) AGAINST ('$q') ORDER BY relevance DESC LIMIT 15
