"在@wiaterb的建议下，我成功地做到了这一点。发布解决方案以帮助其他人。
注意：不需要指定`filterset_fields`。
`views.py`
```python
import django_filters
from django.db.models import Q
from .models import Person
class IDFilter(django_filters.FilterSet):
    id_no = django_filters.CharFilter(method='search_by_id', label='按ID搜索')
    class Meta:
        model = Person
        fields = ['id_no']
    def search_by_id(self, queryset, name, value):
        return queryset.filter(
            Q(passport_no=value) | Q(nic_driving_license=value)
        )
class PersonViewSet(viewsets.ModelViewSet):
    ...
    filterset_class = IDFilter
