Description
The documentation on Base Managers https://docs.djangoproject.com/en/2.2/topics/db/managers/#base-managers is confusing or incomplete.
It specifies "By default, Django uses an instance of the Model._base_manager manager class when accessing related objects (i.e. choice.question), not the _default_manager on the related object."
But when accessing the set of related objects, i.e. question.choice_set, it is the default manager that is used. This does not appear clearly in the documentation.

Hi Benjamin.
This comes up every so often — it's hard stuff.
The docs have:
But I think the required information is really in the Making Queries topic page. I've suggested a PR adding a link back to the Following relationships backward section there. Hopefully that's clearer.
Thanks for the report.
