For parent-child relationships, I found that using a parameterized view works better than a filter. And a SET RELATION is not flexible enough, i.e., there is no easy way to create temporary indices.
Specifically, the parameterized view is much faster than a view, especially for larger tables (more than about 20,000 records).
