It returns an empty set because after the first filter you only have the objects with size=1024, then you are asking to filter out of that set the ones with size=2048. In SQL it would like like "WHERE size = 1024 AND size = 2048". How about something like: models.TestLine.objects.filter(dimm__size__in=[1024, 2048]) Regards Darryl
