jQuery.ajax({
    url : '<portlet:actionURL  windowState="exclusive" >
          <portlet:param name="struts.portlet.action" value="/view/view/search"/>   </portlet:actionURL >' ,
    data : <portlet:namespace/>form_data ,
    success : function (result){
            jQuery("#<portlet:namespace/>search_results").html(result);
            }
        });
