    IndexableField

      public class Geo3DDocValuesField
      extends Field

  An per-document 3D location field.

  Sorting by distance is efficient. Multiple values for the same field in one document is allowed.

  This field defines static factory methods for common operations:

  - TBD

  If you also need query operations, you should add a separate `Geo3DPoint` instance.

  WARNING: Values are indexed with some loss of precision from the original `double` values (4.190951585769653E-8 for the latitude component and 8.381903171539307E-8 for longitude).
