Perhaps you should try some spelling variations:
kur » kurz, kurt, kurs
kurzt » kurzzt, kurtzt, kurszt, kurz, kurze, kurst
kuret » kurzet, kurtet, kurset, kurt, kuren, muret
kurtet » kurztet, kurttet, kurstet, kurten, kartet

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