title: How to retrieve FB comments/shares for a specific URL
body: <p>I would like to retrieve the text,author of comments or shares made for a specific url. 
  I have for instance the following target : <a href="http://www.graphemeride.com/blog/comment-j-ai-triche-aux-golden-blog-awards" rel="nofollow">http://www.graphemeride.com/blog/comment-j-ai-triche-aux-golden-blog-awards</a></p>
  
  <p>I can retrieve the number of comments and shares <a href="https://developers.facebook.com/tools/explorer?fql=SELECT%20%0A%20%20%20%20url,%20share_count%20,%20comment_count,%20comments_fbid%0AFROM%20%0A%20%20%20%20link_stat%20%0AWHERE%20%0A%20%20%20%20url=%22http://www.graphemeride.com/blog/comment-j-ai-triche-aux-golden-blog-awards%22" rel="nofollow">with FQL</a> :</p>
  
  <pre><code>SELECT 
      url, share_count , comment_count, comments_fbid
  FROM 
      link_stat 
  WHERE 
      url="http://www.graphemeride.com/blog/comment-j-ai-triche-aux-golden-blog-awards"
  </code></pre>
  
  <p>I get the following result :</p>
  
  <pre><code>{
    "data": [
      {
        "url": "http://www.graphemeride.com/blog/comment-j-ai-triche-aux-golden-blog-awards",
        "share_count": 27,
        "comment_count": 26,
        "comments_fbid": 357167807708699
      }
    ]
  } 
  </code></pre>
  
  <p>My plan was to use the <a href="https://developers.facebook.com/docs/reference/fql/comment/" rel="nofollow">comment FQL</a> query to <a href="https://developers.facebook.com/tools/explorer?fql=SELECT%20%0A%20%20%20%20id,%20text%0AFROM%20%0A%20%20%20%20comment%0AWHERE%20%0A%20%20%20%20object_id=%22357167807708699%22" rel="nofollow">retrieve the different comments</a>.</p>
  
  <pre><code>SELECT 
      id, text
  FROM 
      comment
  WHERE 
      object_id="357167807708699"
  </code></pre>
  
  <p>However I get an empty result dataset.
  I added the required access token, but kind of understood that I can only get comments I made about this object, not public comments or shares.</p>
  
  <p>Is there an alternative way to get access to what people publicly said about an url ?</p>
