org.apache.lucene.search.Query

org.apache.lucene.spatial.composite.IntersectsRPTVerifyQuery

All Implemented Interfaces:

Cloneable

public class IntersectsRPTVerifyQuery
extends Query

A spatial Intersects predicate that distinguishes an approximated match from an exact match based on which cells are within the query shape. It exposes a TwoPhaseIterator that will verify a match with a provided predicate in the form of a ValueSource by calling FunctionValues.boolVal(int).
