FieldError: Связанное поле получило недействительный поиск: содержит

Я пытаюсь реализовать простой поиск, при котором пользователь вводит любую строку в поисковый ввод и вся таблица проверяется на наличие строки.

Я получаю ошибку -> django.core.exceptions.FieldError: Related Field got invalid lookup: contains. Я пробовал с Q(owner_name__icontains=search_text), но все равно получаю ошибки.

Q(created_by__name__contains=search_text) |
Q(updated_by__name__contains=search_text)
