C# Class Lucene.Net.Spatial.Prefix.RecursivePrefixTreeFilter

Performs a spatial intersection filter against a field indexed with {@link SpatialPrefixTree}, a Trie. SPT yields terms (grids) at length 1 and at greater lengths corresponding to greater precisions. This filter recursively traverses each grid length and uses methods on {@link Shape} to efficiently know that all points at a prefix fit in the shape or not to either short-circuit unnecessary traversals or to efficiently load all enclosed points.
