Perhaps you should try some spelling variations:
kur » kurz, kurt, kurs
kuret » kurzet, kurtet, kurset, kurt, kuren, muret
kurzzt » kurzzzt, kurtzzt, kurszzt, kurzzeit
kurstsen » kurzstsen, kurtstsen, kursstsen, kursten, kurstagen, kursen

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 ((kuret OR kurzzt) OR kurstsen)) OR kaursse).
• Adding a wildcard symbol may retrieve word variants: ((kur or ((kuret or kurzzt) or kurstsen)) or kaursse)*.
