Django Rest Framework does not filter after resetting queryset

My url will be something like: ... /? Search = modal.

I want to replace the "modal" with empty "" to clean the filter and return all records.

Views.py

class AnexoExamesViewSet(viewsets.ModelViewSet):    search_fields = ['descr']  filter_backends = (filters.SearchFilter,)  queryset = AnexoExames.objects.all()  serializer_class = AnexoExamesSerializer    def get_queryset(self):      queryset = AnexoExames.objects.all()      search_descr = self.request.query_params.get('search',None)      print(search_descr)      if search_descr=='modal':                      queryset = AnexoExames.objects.filter(descr='')                      return queryset  

This way it is returning zero results
