TermQueryPrefixTreeStrategy (Lucene 10.5.0 spatial-extras API)
Description: declaration: package: org.apache.lucene.spatial.prefix, class: TermQueryPrefixTreeStrategy

Package org.apache.lucene.spatial.prefix

# Class TermQueryPrefixTreeStrategy

java.lang.Object
org.apache.lucene.spatial.SpatialStrategy
org.apache.lucene.spatial.prefix.PrefixTreeStrategy
org.apache.lucene.spatial.prefix.TermQueryPrefixTreeStrategy

public class TermQueryPrefixTreeStrategy extends PrefixTreeStrategy
A basic implementation of `PrefixTreeStrategy` using a large `TermInSetQuery` of all the cells from `SpatialPrefixTree.getTreeCellIterator(org.locationtech.spatial4j.shape.Shape, int)`. 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.

WARNING: This API is experimental and might change in incompatible ways in the next release.
