Symfony2 createQuery中参数模糊查询

$em = $this->getDoctrine()->getEntityManager();  $query = $em->createQuery(      'SELECT u.user1lname FROM MySiteMyBundle:User u WHERE u.user1lname LIKE :searchTerm ORDER BY u.user1lname ASC'      )->setParameter('searchTerm', $searchTerm.'%');  $result = $query->getResult();
