Comment:
Are you expecting the ORM to issue an `UNION` like the following query?
{{{#!sql
SELECT "auth_user"."first_name" AS "name_field" FROM "auth_user"
UNION
SELECT "auth_user"."last_name" AS "name_field" FROM "auth_user"
}}}
I think the ORM only combines the queries filters when the `|` is used.
