Sunspot with multiple models (in Rails)

Question

Answer 1

I like the idea of a Search object if you are doing any complicated conditions.

But to search across objects using Sunspot:

@sunspot_search = Sunspot.search User, Tag, Product do |query| 
  query.keywords @search_query
  query.with(:age).greater_than 20
  query.with(:age).less_than 25
  query.paginate(:page => params[:page], :per_page => 30)
end
