19. 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).
