title: Solr Faceting result with more than just count
body: <p>This is my requirment:
  I have a list of products indexed in Solr and categoryid, category name and category alias are MultiValued fields.
  I would like to do faceting on category but want the faceting result to have all categoryID, CategoryName and Category Alias along with the count number.
  Is this possible? Or I have to do faceting only for CategoryID and with another request or query to our SQL server database get the rest of the information of that CategoryID?</p>
