  Package | Description
  --- | ---
  org.modeshape.jcr |
  org.modeshape.jcr.query | The Query API provides a mechanism for building and executing queries.
  org.modeshape.jcr.query.lucene | The core query engine, which currently uses Lucene for indexing and raw queries, and the Hibernate Search engine (which does not depend on or use Hibernate Core or JPA) for updating and querying the Lucene indexes.
  org.modeshape.jcr.query.lucene.basic | The "basic" `Lucene schema` has a single index in which all node and property information are indexed into separate fields.
  org.modeshape.jcr.query.model | The Abstract Query Model is a vocabulary that can be used to construct a language-neutral representation of a query.
  org.modeshape.jcr.query.optimize | This package contains the Optimizer interface, a rule-based optimizer implementation, and library of optimization rules.
  org.modeshape.jcr.query.parse | 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.

  org.modeshape.jcr.query.process | This package defines the `QueryProcessor` interface, which is responsible for constructing for each query a tree of `ProcessingComponent` objects that each are responsible for processing a specific aspect of the query and returning the tuples to the parent component.
  org.modeshape.jcr.query.validate | This package provides the interfaces that define the tables and columns that can be queried.
  org.modeshape.jcr.query.xpath | The components used to parse JCR XPath queries and translate them into equivalent JCR-SQL2 queries.
