19. OR lookups
To perform an OR lookup, or a lookup that combines ANDs and ORs, use the
``complex`` keyword argument, and pass it an expression of clauses using the
variable ``django.db.models.Q`` (or any object with a get_sql method).
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
a get_sql method).
