Standard Lucene Query Node Builders.

## Standard Lucene Query Node Builders

The namespace <tt>Lucene.Net.QueryParsers.Flexible.Standard.Builders</tt> 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.
