title: Django Filter all fields of Model
body: <p>i have a short Question.</p>
  <p>I've been working on a Inventory-System to use in my company. So i'm pretty new here and i'm not experienced with Django.</p>
  <p>To filter the items, i made a simple search bar, where you can search for items. The filter looks like this:</p>
  <pre><code>return Item.objects.filter(name__contains=self.request.GET.get('search_item'))
  </code></pre>
  <p>As you see, i only filter by name, but i would like to filter all attributes of <code>Profile</code> with the search-field. Is it possible to check all fields of a Model in a single query?</p>
  <p>Thank you</p>
