Perhaps you should try some spelling variations:
kur » kurz, kurs, kaur
kurtz » kurztz, kurstz, kaurtz, kurz, kurzz
kurt » kurzt, kurst, kaurt, kurz
kursz » kurzsz, kurssz, kaursz, kurs, kurse, kursk
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 ((kurtz OR kurt) OR kursz)) OR kaumsse).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((kur or kar) or ((kurtz OR kurt) or kursz)) or kaumsse)".
• Adding a wildcard symbol may retrieve word variants: (((kur or kar) or ((kurtz OR kurt) or kursz)) or kaumsse)*.
