Ransack search on dynamic routes

i would be able to ransack search on a dynamic route path, and the exemples that i have is using a collection on fixed path like this:

collection do
        post :search, to: 'exemple#index'
      end

so in a Order shop cart exemple like this:

model:

class Order < ActiveRecord::Base
STATUSES = %w(paid sent)
end

controller:

def sent
    order = Order.find(params[:id])

    @q = Order.where('status = ?', params[:status] || Order.statuses[0]).ransack(params[:q])

 @orders = @q.result(distinct: true).paginate(page: params[:page], per_page: 5)

 if order
      order.status = Order.statuses[1]
      order.save
      redirect_to "#{sold_orders_path}?status=#{Order.statuses[0]}",
                  flash: { success: 'State changed' }
    end
  end



view url: orders/sold?status=paid

i would like to know if is possible to use ransack to make this kind of search or i have to scope this out on the model?

thank's
