OR in filters:
1) queryset = User.objects.filter( first_name__startswith='R') | User.objects.filter(last_name__startswith='D')

2)qs = User.objects.filter(Q(first_name__startswith='R')|Q(last_name__startswith='D'))

In both cases SQL query will be the same

AND in filters:

2) queryset_1 & queryset_2
3)filter(Q(<condition_1>) & Q(<condition_2>))
