## Package org.apache.lucene.queryParser.standard Description

Contains the implementation of the Lucene query parser using the flexible query parser frameworks

## Lucene Flexible Query Parser Implementation

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.

The classes contained in the package org.apache.lucene.queryParser.standard are used to reproduce the same behavior as the old query parser.

Check `org.apache.lucene.queryParser.standard.StandardQueryParser` to quick start using the Lucene query parser.

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.
