You're using Q objects, did you not read any of the documentation on them? This is clearly explained[1] in the docs. qfilter = Q(my_field__contains=search_term) if search_date: qfilter |= Q(date_field=search_term) # etc. queryset = MyObject.objects.filter(qfilter) Cheers Tom [1] http://docs.djangoproject.com/en/1.2/topics/db/queries/#complex-lookups-with-q-objects -- You received this message because you are subscribed to the Google Groups "Django users" group.
