C# 클래스 Lucene.Net.QueryParsers.Flexible.Standard.Processors.RemoveEmptyNonLeafQueryNodeProcessor

This processor removes every IQueryNode that is not a leaf and has not children. If after processing the entire tree the root node is not a leaf and has no children, a MatchNoDocsQueryNode object is returned. This processor is used at the end of a pipeline to avoid invalid query node tree structures like a GroupQueryNode or ModifierQueryNode with no children.
