The package org.apache.lucene.queryParser.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 {@link org.apache.lucene.queryParser.standard.processors.StandardQueryNodeProcessorPipeline}.
{@link org.apache.lucene.queryParser.standard.builders.StandardQueryTreeBuilder} is a builder that already contains a defined map that maps each QueryNode object with its respective builder.
