Facebook API - Pulling posts with HashTag

I'm having to apply the facebook API on a site by pulling the posts on a page, I wonder if there's any way to pull only posts containing a HashTag, does the API allow this?

HOW I'M PULLING

In this case, it could be seen working through this link:

  

link ********* / posts? access_token = *********** ** & fields = message, full_picture, link

function fbFeed(){

     var pagina = "***********";
     var token = "************";
     var campos = "fields=message,full_picture,link";
     var limite = "4"

     var url = "https://graph.facebook.com/"+pagina+"/posts?" +
               "access_token="+token+"" +
               "&limit="+limite+"&"+campos+"&callback=?";
