Examples of TermQueryPrefixTreeStrategy

org.apache.lucene.spatial.prefix.TermQueryPrefixTreeStrategy
A basic implementation of {@link PrefixTreeStrategy} using a large {@link TermsFilter} of all the cells from {@link SpatialPrefixTree#getCells(com.spatial4j.core.shape.Shape,int,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. @lucene.experimental
