          Note:
              Post/pre save hooks and signals will NOT triggered.
  
              Unlike RDBMS systems, this method makes individual save calls
              to backend DB store. So this is exists as more of a comfortable
              utility method and not a performance enhancement.

              \*\*kwargs: Fields with their corresponding values to be updated.
  
          Returns:
              Int. Number of updated objects.
  
          Example:
              .. code-block:: python
  
                  Entry.objects.filter(pub_date__lte=2014).update(comments_on=False)
