mysql - Mysql查询匹配和OR WHERE

Question

嗨，如果有这个查询：

 SELECT *,
      MATCH(tags) AGAINST ('book library' IN BOOLEAN MODE) AS resources_score 
      FROM books  HAVING resources_score > 0 
      ORDER BY resources_score DESC, id DESC ; 

是否可以添加一个OR WHERE title LIKE ;

另外，由于我的查询是 returnig resource_score as 1or 0，是否有可能获得更高的查询/搜索/结果准确性？

最后，提示一个问题，查询匹配准确度取决于记录数？

感谢谁会帮助我

Answer 1

当所有其他方法都失败时，您可以使用算术组合 SQL 函数。

 SELECT *,
 (title LIKE '%pattern%') + (MATCH(tags) AGAINST ('book library' IN BOOLEAN MODE))
   AS resources_score 
 FROM books HAVING resources_score > 0 
 ORDER BY resources_score DESC, id DESC ;

当标题包含“模式”时，这将为 MATCH() 返回的分数加 1。
