title: Get content from facebook by hashtag
body: <p>Why is there information about facebook hashtags if it's not supported by the graph API? <a href="https://developers.facebook.com/docs/graph-api/reference/hashtag" rel="nofollow">https://developers.facebook.com/docs/graph-api/reference/hashtag</a> Is there a way to get images and content by hashtag?</p>
  
  <p>I.e #summerhangout:</p>
  
  <pre><code>/* PHP SDK v4.0.0 */
  /* make the API call */
  $request = new FacebookRequest(
    $session,
    'GET',
    '/%23summerhangout'
  );
  $response = $request-&gt;execute();
  $graphObject = $response-&gt;getGraphObject();
  /* handle the result */
  </code></pre>
  
  <p>Result:</p>
  
  <pre><code>Fatal error:  Uncaught exception 'Facebook\FacebookAuthorizationException' with message '(#803) Some of the aliases you requested do not exist: #summerhangout' in /Library/WebServer/Documents/projname/vendor/facebook/php-sdk-v4/src/Facebook/FacebookRequestException.php:134
