通過連接表搜索只顯示一個表的數據匹配

Question

我試圖執行與下面的查詢搜索：

 SELECT 
      * 
     FROM 
      question_index 
     JOIN 
      question_content 
      ON question_index.id = question_content.question_id 
     WHERE 
      question_index.remove = '0' AND 
      question_index.active = '1' AND   
      question_index.publish_date <= '$current_time' AND 
      (
       question_index.question LIKE '%$keyword%' OR 
       question_content.text LIKE '%$keyword%' 
      ) 
     GROUP BY 
      question_index.id 
     ORDER BY 
      question_index.publish_date DESC 

我想要做的是關於搜索通過表和顯示運行結果匹配「question_index.question」或「question_content.text」

但現在，它只顯示匹配「question_content.text」的結果。我試圖刪除「question_content.text LIKE'％$ keyword％'」但沒有結果出現。我可以得到匹配「question_index.question」結果的唯一方法是如果我一起刪除聯接。但那不是我想要的結果。

SELECT 
     * 
    FROM 
     question_index LEFT 
    JOIN 
     question_content 
     ON question_index.id = question_content.question_id 
    WHERE 
     question_index.remove = '0' AND 
     question_index.active = '1' AND   
     question_index.publish_date <= '$current_time' AND 
     (
      question_index.question LIKE '%$keyword%' OR 
      question_content.text LIKE '%$keyword%' 
     ) 
    GROUP BY 
     question_index.id 
    ORDER BY 
     question_index.publish_date DESC
