如何使用Twitter流媒体API？

stream.filter(locations=[-122.75,36.8,-121.75,37.8,-74,40,-73,41],track=["twitpic"])

This Works。但是，这不是“与”。这是“或”。该行获取位置OR关键字。如何制作“AND”？如何使用Twitter流媒体API？

这里的代码库我使用：

def filter(self, follow=None, track=None, async=False, locations=None): 
     self.parameters = {} 
     self.headers['Content-type'] = "application/x-www-form-urlencoded" 
     if self.running: 
      raise TweepError('Stream object already connected!') 
     self.url = '/%i/statuses/filter.json?delimited=length' % STREAM_VERSION 
     if follow: 
      self.parameters['follow'] = ','.join(map(str, follow)) 
     if track: 
      self.parameters['track'] = ','.join(map(str, track)) 
     if locations and len(locations) > 0: 
      assert len(locations) % 4 == 0 
      self.parameters['locations'] = ','.join(['%.2f' % l for l in locations]) 
     self.body = urllib.urlencode(self.parameters) 
     self.parameters['delimited'] = 'length' 
     self._start(async)
