func (*Store) GetMovies 

func (s *Store) GetMovies(year int32, title string) ([]StoreMovie, error)

Movies returns the store's inventory. The year and title can be used to constrain the results, but because we apply this constraint to the sort key, the year must be specified, and if title is specied, any movie titles with that prefix will be returned. Obviously, this is only an exercise in DDB query techniques, and very much not a practical general-purpose search capability.
