public abstract class PointInSetQuery extends Query
IntPoint,
is contained in the specified set.
This is for subclasses and works on the underlying binary encoding: to
create range queries for lucene's standard Point types, refer to factory
methods on those classes, e.g. IntPoint.newSetQuery() for
fields indexed with IntPoint.

QueryQueryCache works properly.
Typically a query will be equal to another only if it's an instance of
the same class and its document-filtering properties are identical that other
instance. Utility methods are provided for certain repetitive code.equals in class QueryQuery.sameClassAs(Object),
