Perhaps you should try some spelling variations:
kur » kurz, kurt, kurs
kuret » kurzet, kurtet, kurset, kurt, kuren, muret
kurtet » kurztet, kurttet, kurstet, kurten
kurtzt » kurztzt, kurttzt, kurstzt, kurtzte, kurtz, kurtze
kartet » kartei, kartel

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