title: fql OR and order by desc with offset
body: <p>I have some issue with a Facebook's fql request :).</p>
  
  <p>When I request like this</p>
  
  <blockquote>
    <p>SELECT uid, profile_url
    FROM user where contains('potatoe') OR uid in(select id from profile where contains ('potatoe'))
    ORDER BY mutual_friend_count desc LIMIT 0,2</p>
  </blockquote>
  
  <p>I have always the same results, even if I change the offset...</p>
  
  <p>But</p>
  
  <ul>
  <li>If I change DESC to ASC the "offset" works...</li>
  <li>If I change OR to AND
  and let the order by desc => the "offset" works too!</li>
  </ul>
  
  <p>Something is wrong with my OR/desc/offset combo?
  Or I just have misunderstood something with "or" operators? :/</p>
  
  <p>Thanks a lot.</p>
