title: Facebook Topic Search API not working
body: <p>I need to build an application which needs to search in public Facebook posts.</p>
  
  <p>As I search for solution I found the Topic Search API: <a href="https://developers.facebook.com/docs/topic_search/v2.4" rel="nofollow">https://developers.facebook.com/docs/topic_search/v2.4</a></p>
  
  <p>I tried this API using a Facebook Application but getting this error:</p>
  
  <pre><code>{
    "error": {
      "message": "(#3) Application does not have the capability to make this API call.",
      "type": "OAuthException",
      "code": 3
    }
  }
  </code></pre>
  
  <p>How can I gain access to use the search API?</p>
