Perhaps you should try some spelling variations:
kur » kurz, kurt, kurs
kurze » kurzze, kurtze, kursze, kurz
kuret » kurzet, kurtet, kurset, kurt, kuren, muret
kurtztet » kurztztet, kurttztet, kurstztet, kurtzte, kurtze, kurtzer

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((kur OR (kurze OR (kuret OR kurtztet))) OR kaursse).
• Adding a wildcard symbol may retrieve word variants: ((kur or (kurze or (kuret or kurtztet))) or kaursse)*.
