Class TermQueryPrefixTreeStrategy

A basic implementation of PrefixTreeStrategy using a large Lucene.Net.Queries.TermsFilter of all the cells from GetCells(IShape, Int32, Boolean, Boolean). It only supports the search of indexed Point shapes.

The precision of query shapes (DistErrPct) is an important factor in using this Strategy. If the precision is too precise then it will result in many terms which will amount to a slower query.

This is a Lucene.NET EXPERIMENTAL API, use at your own risk
