如何在WHERE條件或HAVING條件下搜索可返回true的值？

Question

我想搜索多個變量，在WHERE條件下或在HAVING條件下，在group_concat表中可能爲true。事情是這樣的：

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 

有一些可能的方式還是好做2個querys？

這個查詢：

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 

找到我尋找，但我必須做第二次查詢，顯示結果我想要的。

對不起，如果問題重複，我不知道該怎麼去問，所以我不知道如何去搜索它。對不起我的英文！

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)
