Fromreading here I understood that I have to useall=True if I want to get all results, and then doas_list=False to get a generator to iterate over. But in fact this does not work well together. By specifyingall=True it first starts fetching all results and generator does not call anything with results as pages are coming in.

I thinkall=True should just work withas_list=False. If I understand correctly,all=True is a noop in that case becauseas_list=False already implies it?
