title: Getting limited number of posts using Facebook Graph API
body: <p>I'm getting limited number of posts (for a Facebook page, here 'Walmart') while querying using Facebook Graph API. I'm using <a href="https://github.com/pythonforfacebook/facebook-sdk" rel="nofollow">https://github.com/pythonforfacebook/facebook-sdk</a></p>
  
  <pre><code>graph = facebook.GraphAPI(oath_access_token)
  feed = graph.get_object('/walmart/' + 'posts', since='2013-01-01', until='2014-01-10', limit=500)
  </code></pre>
  
  <p>If I don't use limit, I get only 25 posts, which is default. If I put limit to some high value like 500, I only get 168 posts. These 168 posts are from '2013-12-20' to '2014-01-09'. So effectively I'm missing posts between '2013-01-01' to '2013-12-19'.</p>
