All Implemented Interfaces:
Serializable, Cloneable, FieldableNode, QueryNode, TextableQueryNode

public class PrefixWildcardQueryNode
extends WildcardQueryNode

A PrefixWildcardQueryNode represents wildcardquery that matches abc* or *. This does not apply to phrases, this is a special case on the original lucene parser. TODO: refactor the code to remove this special case from the parser. and probably do it on a Processor
