C# Class Lucene.Net.Spatial.Vector.PointVectorStrategy

Simple {@link SpatialStrategy} which represents Points in two numeric {@link DoubleField}s. Note, currently only Points can be indexed by this Strategy. At query time, the bounding box of the given Shape is used to create {@link NumericRangeQuery}s to efficiently find Points within the Shape. Due to the simple use of numeric fields, this Strategy provides support for sorting by distance through {@link DistanceValueSource}
