title: Facebook API search for hashtag does not show all the post
body: <p>I am fetching all public post with specific hashtag. The problem is that the result only shows some of the post but not all. </p>
  
  <p>It is any restrictions or rules in what post are indexed and show in the "search".</p>
  
  <p>I'm using <a href="https://graph.facebook.com/search?q=myhashtag&amp;type=post" rel="nofollow">https://graph.facebook.com/search?q=myhashtag&amp;type=post</a>.</p>
  
  <p>What I can see so far is that in the facebook page when I search for the hashtag I have some results and they are different that the ones the api returns.</p>
