Perhaps you should try some spelling variations:
kur » kurt, kurs
kursat » kurtsat, kurssat, kursad
kurz » kurtz, kursz
kurzest » kurtzest, kurszest, kurzeste, kurztest, kurzes
kaur » kaum, kauf, kar
kaursse » kaumsse, kaufsse, karsse
karsse » karssen, karosse

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