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.
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.
||This interface describes a character stream that maintains line and
column number positions of the characters.
||Token literal values and constants.
||This exception is thrown when parse errors are encountered.
