Detailed Description

Simple SpatialStrategy which represents Points in two numeric DoubleFields.

Note, currently only Points can be indexed by this Strategy. At query time, the bounding box of the given Shape is used to create NumericRangeQuerys to efficiently find Points within the Shape.

Due to the simple use of numeric fields, this Strategy provides support for sorting by distance through DistanceValueSource
