+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).
