Yes, it can be done using DQL. Doctrine does not support IF statement. But same functionality can be achieved by CASE statement. Sample DQL is given bellow,

$dql = "SELECT t, 
          (CASE 
            WHEN (t.name LIKE :searchterm) THEN 10 
            ELSE 0
          END) + 
          (CASE 
            WHEN (t.address LIKE :searchterm) THEN 5 
            ELSE 0
          END) + 
          (CASE 
            WHEN (t.city LIKE :searchterm) THEN 1 
            ELSE 0
          END)
          AS weight 
        FROM YourBundleName:TableName t 
        WHERE 
          t.name LIKE :searchterm OR 
          t.address LIKE :searchterm OR 
          t.city LIKE :searchterm
        ORDER BY weight DESC
      ";
$query = $entityManager->createQuery($dql)
  ->setFirstResult(0)
  ->setMaxResults(20)
  ->setParameter('searchterm' , $searchterm)
  ;
