The .all() method returns a QuerySet[1] object.  You can also use

   book.object.filter(title="One Fish, Two Fish")
   book.object.exclude(title="Green Eggs & Ham")

which also return a QuerySet objects, so they can be chained:

   book.object.filter(author="Seuss").exclude(title="Green Eggs & 
Ham")

Reading the linked page should give you an abundance of examples 
on how to use these QS objects.
