如何在WHERE条件或HAVING条件下搜索可返回true的值？

Question

我想搜索多个变量，在WHERE条件下或在HAVING条件下，在group_concat表中可能为true。事情是这样的：

SELECT 
    article.id, 
    article.name, 
    GROUP_CONCAT(tags.name order by tags.name) AS nameTags, 
    GROUP_CONCAT(tags.id order by tags.id) AS idTags 
FROM 
    article 
    LEFT JOIN .... 
    LEFT JOIN .... 
WHERE article.name LIKE '%var1%' OR HAVING nameTags LIKE '%var1%' AND 
WHERE article.name LIKE '%var2%' OR HAVING nameTags LIKE '%var2%' 
GROUP BY id 

有一些可能的方式还是好做2个querys？

这个查询：

SELECT 
    article.id, 
    article.name, 
    GROUP_CONCAT(tags.name order by tags.name) AS nameTags, 
    GROUP_CONCAT(tags.id order by tags.id) AS idTags 
FROM 
    article 
    LEFT JOIN .... 
    LEFT JOIN .... 
WHERE 
(article.name LIKE '%var1%' OR tags.name LIKE '%var1%') AND 
(article.name LIKE '%var2%' OR tags.name LIKE '%var2%') 
GROUP BY id 

找到我寻找，但我必须做第二次查询，显示结果我想要的。

对不起，如果问题重复，我不知道该怎么去问，所以我不知道如何去搜索它。对不起我的英文！

SELECT 
    article.id, 
    article.name, 
    GROUP_CONCAT(tags.name order by tags.name) AS nameTags, 
    GROUP_CONCAT(tags.id order by tags.id) AS idTags, 
    MAX(IF(article.name LIKE '%var1%',1,0)) AS var1match, 
    MAX(IF(article.name LIKE '%var2%',1,0)) AS var2match 
FROM 
    article 
    LEFT JOIN .... 
    LEFT JOIN .... 
GROUP BY id 
HAVING 
    (nameTags LIKE '%var1%' OR var1match=1) 
    OR (nameTags LIKE '%var2%' OR var2match=1)
