Standard Lucene Query Node Builders.

## Standard Lucene Query Node Builders

 The package org.apache.lucene.queryparser.flexible.standard.builders contains all the builders needed to build a Lucene Query object from a query node tree. These builders expect the query node tree was already processed by the <xref:Lucene.Net.QueryParsers.Flexible.Standard.Processors.StandardQueryNodeProcessorPipeline>. 

 <xref:Lucene.Net.QueryParsers.Flexible.Standard.Builders.StandardQueryTreeBuilder> is a builder that already contains a defined map that maps each QueryNode object with its respective builder.
