title: Facebook Comments Count
body: <p>I am trying to write a Facebook query that will return all comments posted by a user to his friends,</p>
  
  <p>however I can't seem to find the correct schema. Its as if there are no 'indexable' fields to build this.</p>
  
  <p>Any suggestions please?</p>
  
  <p>With thanks,</p>
