import django_filters.rest_framework
class searchView(viewsets.ModelViewSet):
filter_backends = (django_filters.rest_framework.DjangoFilterBackend,filters.OrderingFilter,)

Alternatively, you could do

from django_filters.rest_framework import DjangoFilterBackend
class searchView(viewsets.ModelViewSet):
filter_backends = (DjangoFilterBackend, filters.OrderingFilter,)
