Class: Sunspot::Type::LocationType

Inherits:
AbstractType show all
Defined in:
lib/sunspot/type.rb

Overview

The Location type encodes geographical coordinates as a GeoHash. The data for this type must respond to the ‘lat` and `lng` methods; you can use Sunspot::Util::Coordinates as a wrapper if your source data does not follow this API.

Location fields are most usefully searched using the Sunspot::DSL::RestrictionWithType#near method; see that method for more information on geographical search.

Example

Sunspot.setup(Post) do
  location :coordinates do
    Sunspot::Util::Coordinates.new(coordinates[0], coordinates[1])
  end
end
