This module provides our base classes for query backends as well as helper functions.


Given an iterable of EPISODES and a USER, return a filtered list of episodes that this user has the permissions to know about.

filtered_episodes = episodes_for_user(episodes, user)


Given a partial fragment for example Jane 123, return all patients that have either a first name, last name or hospital number including jane or 123. Under the covers it uses Patient.objects.search. It then orders patients by which have had their episodes created most recently.
