	 * The built-in queries iterate over all instances.

	 * This is similar to the {@link Filter} interface in the applib, except the
	 * filtering is done within the object store as opposed to be the
	 * {@link DomainObjectContainer}.
	 * 
	 * 
	 * Object store implementations do not necessarily need to rely on this
	 * method. For example, an RDBMS-based implementation may use an alternative
	 * mechanism to determine the matching results, for example using a
	 * WHERE clause in some SQL query.
