总和匹配相关性不起作用

Question

我正在使用带有Doctrine的Symfony2.7。我的查询工作没有在ORDER BY部分中进行相关性的总和。

有什么问题？ Doctrine不支持一笔款项吗？

SELECT s.shopArticleId as article_id, 
   MATCH (s.soundex, s.categorySoundex) AGAINST ('T200') AS relevance1,
   MATCH (s.soundex, s.categorySoundex) AGAINST ('A530') AS relevance2

FROM FrontendMainBundle:Search s 

WHERE MATCH (s.soundex, s.categorySoundex) AGAINST ('T200') > 0 
AND MATCH (s.soundex, s.categorySoundex) AGAINST ('A530') > 0 

ORDER BY (relevance1 + relevance2) DESC;
