Perhaps you should try some spelling variations:
kur » kurz, kurt, kurs
kurschat » kurzschat, kurtschat, kursschat, kurshan
kursat » kurzsat, kurtsat, kurssat, kursad
kuret » kurzet, kurtet, kurset, kurt, kuren, muret
warschat » warschau, bartschat, marschak

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