## Package org.modeshape.graph.query.parse Description

This package defines the `QueryParser` interface, which defines a component that can parse a query represented in a specific language and produce the corresponding `abstract query model` representation.

Several parsers are provided, including one that parses a subset of SQL and another that parses the full-text search expressions. However, other query parsers can easily be created and used.
