title: how to restrict facebook graph search to cities only
body: <p>We're have a web-app that uses Facebook connect and is using FB graph via JS &amp; http. We want to enable the user to publish a post on his timeline that will include a city pinpoint location map. Facebook Docs says <a href="https://developers.facebook.com/docs/reference/api/user/#posts" rel="nofollow">here</a> that for the 'place' parameter in creating posts, I need to write the Facebook Page ID, which I want the user to pick from a list (otherwise how will i get the page ID right?...) so for instance Londone, I should use - <a href="https://www.facebook.com/pages/London-United-Kingdom/210582665626133" rel="nofollow">210582665626133</a>, so I assume I need to use - graph.facebook.com/search?q=london&amp;type=place to get a json lookup of places.
  this brings me to my question - How can I restrict search results to show only cities?
  If there isn't a way to specify this as a parameter on the graph call, and assuming I'd have to filter those on the client, then what is the category or any other method to spot a city out of the clutter of irrelevant places?
  cheers :)</p>
