php如何以單元2全文搜索並按日期排序？

Question

我想做一個全文搜索，有2個組搜索查詢，一個搜索匹配詞'Harry'和'potter'，第二個搜索查詢只匹配單詞'Rowling'。如何將它們和order dy date？那麼$query1 relevance is 70%，$query1 relevance is 30%？謝謝。

$query1 = "SELECT * FROM articles WHERE MATCH (title,content) AGAINST ('+Harry +potter' IN BOOLEAN MODE)";//all the articles both match word 'Harry' and 'potter' 
$query2 = "SELECT * FROM articles WHERE MATCH (title,content) AGAINST ('+Rowling' IN BOOLEAN MODE)";//all the articles macth 'Rowling' 

Answer 1

這兩個查詢都從同一個表中選擇行並設置相同的列。關於UNION呢？

$query = "SELECT * FROM articles WHERE MATCH (title,content) AGAINST ('+Harry +potter' IN BOOLEAN MODE) 
UNION 
SELECT * FROM articles WHERE MATCH (title,content) AGAINST ('+Rowling' IN BOOLEAN MODE)";
