Perhaps you should try some spelling variations:
kur » kurz, kurt, kurs
kuret » kurzet, kurtet, kurset, kurt, kuren, muret
kurzet » kurzzet, kurtzet, kurszet, kurzest, kurzer, kurzen
kurzzt » kurzzzt, kurtzzt, kurszzt, kurzzeit
kurtsen » kurztsen, kurttsen, kurstsen, kursen, kurtzen, kurten

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 kurzet) OR kurzzt) OR kurtsen)) OR kaursse).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((kur or (((kuret OR kurzet) or kurzzt) or kurtsen)) or kaursse)".
• Adding a wildcard symbol may retrieve word variants: ((kur or (((kuret OR kurzet) or kurzzt) or kurtsen)) or kaursse)*.
