## Package org.apache.lucene.queryParser Description

A simple query parser implemented with JavaCC.

Note that JavaCC defines lots of public classes, methods and fields that do not need to be public. These clutter the documentation. Sorry.

Note that because JavaCC defines a class named `Token`, `org.apache.lucene.analysis.Token` must always be fully qualified in source code in this package.

NOTE: contrib/queryparser has an alternative queryparser that matches the syntax of this one, but is more modular, enabling substantial customization to how a query is created.
