"""
OR lookups

To perform an OR lookup, or a lookup that combines ANDs and ORs, combine
``QuerySet`` objects using ``&`` and ``|`` operators.

Alternatively, use positional arguments, and pass one or more expressions of
clauses using the variable ``django.db.models.Q`` (or any object with an
``add_to_query`` method).
