Perhaps you should try some spelling variations:
kur » kurt, kurs, kaur
kurz » kurtz, kursz, kaurz
kuret » kurtet, kurset, kauret, kurt, kuren, muret
kurtet » kurttet, kurstet, kaurtet, kurten, kartet
kar » karl

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