Filters a queryset in order to produce a different set of document from subsequent queries.

User.objects.filter(first_name="Bernardo").filter(last_name="Bernardo").find_all(callback=handle_all)

User.objects.filter(first_name="Bernardo", starting_year__gt=2010).find_all(callback=handle_all)
The available filter options are the same as used in MongoEngine.
