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 » turin, tures, turnn, tuben, tunen
ture » turn, tube, tune

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 ture))) 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 ture))) or kaursse)".
• Adding a wildcard symbol may retrieve word variants: (((kur or kurs) or ((kurzt or kurzzt) or (turen OR ture))) or kaursse)*.
