title: Doctrine2 DQL issue with COUNT = 0
body: <p>I have the following query so far:</p>
  
  <pre><code>   $shopQuery = $qb-&gt;select('DISTINCT u')
                      -&gt;from("BlahUserBundle:User", 'u')
                      -&gt;innerJoin('u.followers', 'followers')
                      -&gt;andWhere('followers.id != :userId')
                      -&gt;setParameter('userId', $user-&gt;getId())
                      -&gt;orWhere('') //or where those user who doesn't have a follower yet
                      //-&gt;setMaxResults(5)
                      ;
  </code></pre>
  
  <p>I am trying to find a way to query all users who doesn't have a follower and whose follower is not my self (in this case my self is <code>$user-&gt;getId()</code>). How do I do so?</p>
