php - 按全文最大匹配排序

Question

我正在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

您可以通过添加或添加升序或降序ORDER BY mat DESC ORDER BY mat

Answer 2

尝试这个

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