Perhaps you should try some spelling variations:
kur » kurz, kurt, kaur
kurs » kurzs, kurts, kaurs, kurz, kurt
kurzt » kurzzt, kurtzt, kaurzt, kurz, kurze, kuret
kurzzt » kurzzzt, kurtzzt, kaurzzt, kurzzeit
turen » ture, turin, tures

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