If it's all the same class, then don't index children:
def ferret_enabled?(is_rebuild = false)
@ferret_disabled.nil? && self.root?
end
Only root nodes would get indexed with the above method (and an
appropriate root? definition) in place.
AFAIK, there is no group_by concept in aaf. At the same time, I don't
think it's really necessary. The above, combined with a single method
definition for children_titles_with_spaces should get you exactly what
you're looking to do.
