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
kursz » kurzsz, kurtsz, kurssz, kurs, kurse, kurtz

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 bauens) OR ((kurzt OR kuret) OR kursz)) OR kaursse)*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((kur or bauens) or ((kurzt OR kuret) or kursz)) or kaursse)*".
