title: Django "OR" like statement in Queryset?
body: <p>Just have a simple syntax question onto Django,
  imagining the following queryset:</p>
  <pre><code>queryset = Requests.objects.get_queryset().filter(
      status='Pending',
      up_rank__gte=config.REQ_RANK - 10,
      down_rank__gte=config.REQ_RANK - 10
  )
  </code></pre>
  <p>Is there any way that I can setup my query like that:</p>
  <blockquote>
  <p>up_vote__gte=config.REQ_RANK - 10 OR down_vote__gte=config.REQ_RANK -
  10 ?! (See pseudo OR)</p>
  </blockquote>
  <p>As I want to filter onto both, up_rank and down_rank __gte. The only way I know would be a query chain but to me that seems not to be efficient, Is there any other way than a query chain statement or do I just talk nonsense and chain is fine?</p>
  <p>Thanks in advance</p>
