Ticket #186 (assigned enhancement)

Description

Let's suppose you have 20000 entries in your database and you have to rebuild the index. The model is:

class Book < ActiveRecord::Base

belongs_to :author acts_as_ferret :fields => [:title, :author_name]

def author_name

return "#{self.author.first_name} #{self.author.last_name}"

end

end

So it will do 20000 + 20 queries in the database (if the batch_size is 1000) because rebuild_index doesn't get associations. If we can set :include => :book (maybe in acts_as_ferret options) it will reduce the queries total to only 20!
