Description

​https://docs.djangoproject.com/en/1.9/ref/models/options/#ordering

Mistakenly, I was thinking that if no ordering was given on a Model's Meta, ordering is by "-id". I was foolishly mistaken. My proposal is to add to the documentation:

"If no ordering is given, results are returned from the database as is. Ordering might be anything, semi-randomly."
