I have the following model set up:

class Business
   has_many :locations
end

class Location
   belongs_to :business
end

Location has latitude and longitude values as radians. I would like to
"geo search" across all the locations when I do Business.search. Is
this possible? If so, can you show me how to do the define_index in
Business class? I'm thinking of something like:

define_index do
   indexes locations.lat, :as => :latit
   indexes locations.lng, :as => :longit
end

Please let me know if I'm in the right direction.

Thank you in advance.
