主義和查詢功能的Symfony2

Question

我已經在我的網頁搜索欄和動作我負責找用戶搜索就是這樣的：

public function searchAction(Request $request){ 

     $em = $this->container->get('doctrine')->getEntityManager(); 

     $evenements= $em->getRepository('Mql14mqlmeBundle:Evenement')->findAll(); 
     if ('POST' === $request->getMethod()) { 

      $search = $request->get('search'); 
    $query = $this->container->get('doctrine')->getEntityManager()->createQuery('SELECT e FROM Mql14mqlmeBundle:Evenement e WHERE e.nom LIKE :search') 
      ->setParameter('search', $search); 
     $resultats = $query->getResult(); 



     return $this->container->get('templating')->renderResponse('Mql14mqlmeBundle:Event:search.html.twig', array(
      'resultats'=>$resultats, 

     )); 

     } 
    return $this->listerAction(); 
     } 

它的工作，如果用戶把確切名稱

$query = $this->container->get('doctrine')->getEntityManager()->createQuery('SELECT e FROM Mql14mqlmeBundle:Evenement e WHERE e.nom LIKE :%search%') 
       ->setParameter('search', $search); 

但我發現了這個錯誤：無效參數：格式數據庫中的某些事件，但我想使搜索可能的，即使這僅僅是名稱的一部分，我在查詢嘗試這個，：給定，但是：name或？num expected。

嘗試改變參數如下：

$query = $this 
    ->container 
    ->get('doctrine') 
    ->getEntityManager() 
    ->createQuery(
     'SELECT e FROM Mql14mqlmeBundle:Evenement e WHERE e.nom LIKE :search' 
    ) 
    ->setParameter('search', '%'.$search.'%');
