      org.jboss.dna.search.lucene.query.NotQuery

All Implemented Interfaces:

Serializable, Cloneable

public class NotQuery
extends org.apache.lucene.search.Query

A Lucene Query implementation that is used to represent a NOT expression of another wrapped Query object. This query implementation works by using the weight and scorer of the wrapped query to score (and return) only those documents that were not scored by the wrapped query. In other words, if the wrapped query ended up scoring any document, that document is not scored (i.e., skipped) by this query.
