title: How to use OR using Django's model filter system?
body: <p>It seems that Django's object model filter method automatically uses the AND SQL keyword. </p>
  
  <p>For example:</p>
  
  <pre><code>&gt;&gt;&gt; Publisher.objects.filter(name__contains="press", country__contains="U.S.A")
  </code></pre>
  
  <p>will automatically translate into something like:</p>
  
  <pre><code>SELECT ... 
  FROM publisher
  WHERE name LIKE '%press%'
  AND country LIKE '%U.S.A.%'
  </code></pre>
  
  <p>However, I was wondering whether there was a way to make that 'AND' an 'OR'? I can't seem to find it in the documentation (oddly enough, searching for 'or' isn't really useful). </p>
