Perhaps you should try some spelling variations:
kur » kurz, kurt, kurs
kurzen » kurzzen, kurtzen, kurszen, kurzer
kurszen » kurzszen, kurtszen, kursszen, kursen, korszen, kurszeg
kurzzt » kurzzzt, kurtzzt, kurszzt, 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 (((kurzen OR kurszen) OR kurzzt) OR turen)) OR kaursse).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((kur or (((kurzen OR kurszen) or kurzzt) or turen)) or kaursse)".
• Adding a wildcard symbol may retrieve word variants: ((kur or (((kurzen OR kurszen) or kurzzt) or turen)) or kaursse)*.
