Default Sorting instructions

[stan74fr]

Hi there
I am implementing filteriffic. I am looking at the example.
I have no need to have the user change the default sorting. before implementation this is what my index was retrieving
@contacts = Contact.order('last_name ASC').order('first_name ASC').paginate(page: params[:page])

how could i keep on having the same after filterffic implementation only for searching in that pre-sorted table. best
