All Implemented Interfaces:

PlanHashable

@API(UNSTABLE)
public class LuceneNotQuery
extends LuceneBooleanQuery

Binder for a negation of clauses. Because of the way Lucene BooleanQuery works, this actually represents set subtraction, with a set of positive and negative clauses. For the same reason, there is no disjunctive analogue.
