Class PrefixWildcardQueryNode
java.lang.Object
org.apache.lucene.queryParser.core.nodes.QueryNodeImpl
org.apache.lucene.queryParser.core.nodes.FieldQueryNode
org.apache.lucene.queryParser.standard.nodes.WildcardQueryNode
org.apache.lucene.queryParser.standard.nodes.PrefixWildcardQueryNode
- All Implemented Interfaces:
- Serializable, Cloneable, FieldableNode, FieldValuePairQueryNode<CharSequence>, QueryNode, TextableQueryNode, ValueQueryNode<CharSequence>
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
