How to make a request from one model to another in ModelAdmin?

Question

Django

There are 2 models:

class Person:
  name = models.CharField()
  surname = models.CharField()
  some_id = models.CharField()

class Player:
  person = models.ForeignKey(Person)
  some_field = models.CharField()

In the admin, on the Records page for the Player, I want to search for Person (any of the specified fields). I found in the documentation that there is a get_search_results method for this, but it only works for its own model.
Here's a code example from the admin (slightly modified) that I want to set up to search for another model, not self.model.

class PlayerAdmin(admin.ModelAdmin):
    def get_search_results(self, request, queryset, search_term):
        queryset, use_distinct = super(PlayerAdmin, self).get_search_results(request, queryset, search_term)
        try:
            print(search_term)
        except ValueError:
            pass
        else:
            queryset |= Person.objects.filter(some_id=search_term) # здесь указал другую модель
        return queryset, use_distinct

What I get: Cannot combine queries on two different base models.
Tell me how it's done? With OOP is not very strong yet. Thanks in advance!
