title: Python Twitter search.tweets with until
body: <p>I am using Python Twitter search api from <a href="https://github.com/sixohsix/twitter" rel="nofollow">https://github.com/sixohsix/twitter</a></p>
  
  <p>When I try to search for a query using the "until" parameter, the search does not return anything</p>
  
  <pre><code>from twitter import *
  
  t = Twitter(auth=OAuth(....))
  
  t.search.tweets(q = 'hello', count=3, until='2012-01-01')
  {u'search_metadata': {u'count': 3, u'completed_in': 0.007, u'max_id_str': u'9223372036854775807', u'since_id_str': u'0', u'refresh_url': u'?since_id=9223372036854775807&amp;q=hello%20until%3A2012-01-01&amp;include_entities=1', u'since_id': 0, u'query': u'hello+until%3A2012-01-01', u'max_id': 9223372036854775807L}, u'statuses': []}
  </code></pre>
  
  <p>while when I search without "until", it finds tweets normally. When I try the search manually on twitter.com/search</p>
  
  <pre><code>https://twitter.com/search?q=hello%20until%3A2012-01-01&amp;src=typd
  </code></pre>
  
  <p>it also finds tweets normally.</p>
  
  <p>Any ideas?</p>
