Perhaps you should try some spelling variations:
kur » kurs
kuret » kurset, kuren, muret, furet
kurz » kursz
kurt » kurst
kurzssz » kurszssz, kurzsitz
kaur » kaum, kauf, kar
kaursse » kaumsse, kaufsse, karsse

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