title: Extracting data from a mongo collection
body: <p>I'm collecting real-time tweets and storing into a collection I now want to extract the information from a record in the collection:</p>
  
  <pre><code>  "place" : { "country_code" : "US", "url" : "http://api.twitter.com/1/geo   /id/01fbe706f872cb32.json", "country" : "United States", "place_type" : "city",  "bounding_box" : { "type" : "Polygon", "coordinates" : [  [ [     -77.119759,      38.791645 ],   [   -76.909393,     38.791645 ],    [   -76.909393,     38.995548  ],   [   -77.119759,     38.995548 ] ] ] }, "full_name" : "Washington, DC",  "attributes" : { }, "id" : "01fbe706f872cb32", "name" : "Washington" }
  </code></pre>
  
  <p>I just want the coordiante information, so using pymongo I try to do:</p>
  
  <pre><code> cursor = coll.find({"place.bounding_box.type" : "Polygon"},{"coordinates" : 1}, tailable = True, timeout = False)
  </code></pre>
  
  <p>But this doesn't return the coordinates where the bounding box is the key.</p>
  
  <p>How could I get this data returned?</p>
  
  <p>Thanks</p>
