Perhaps you should try some spelling variations:
kur » kurz, kurs, kaur
kurt » kurzt, kurst, kaurt, kurz
kuret » kurzet, kurset, kauret, kuren, muret, furet
kurttset » kurzttset, kursttset, kaurttset, kurztset
kurzzt » kurzzzt, kurszzt, kaurzzt, kurzzeit
kurzsen » kurzzsen, kurszsen, kaurzsen

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