     330    >>> Book.objects.filter(name__startswith="Django",
     331                    pages__gt=100).annotate(num_authors=Count('authors'))
     332    # Annotated list of all books with a title starting with "Django" *as well as* all books with more than 100 pages.
     333    >>>Book.objects.filter(name__startswith="Django").filter(
