+Contains the implementation of the Lucene query parser using the flexible query parser frameworks
+
+<h2>Lucene Flexible Query Parser Implementation</h2>
+<p>
+The old Lucene query parser used to have only one class that performed
+all the parsing operations. In the new query parser structure, the
+parsing was divided in 3 steps: parsing (syntax), processing (semantic)
+and building.
+</p>
+<p>
+The classes contained in the package org.apache.lucene.queryParser.standard
+are used to reproduce the same behavior as the old query parser.
+</p>
+
+<p>
+Check <tt>org.apache.lucene.queryParser.standard.StandardQueryParser</tt> to quick start using the Lucene query parser.
+</p>
+
+<p>
+There are 2 wrapper classes that extends QueryParser and MultiFieldQueryParser.
+The classes implement internally the new query parser structure. These 2
+classes are deprecated and should only be used when there is a need to use the
+old query parser interface.
