QueryOnly implemented by primitive queries, which re-write to themselves.

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),
