Perhaps you should try some spelling variations:
kur » kurt
kurz » kurtz
kurs » kurts, kurt
kurzest » kurtzest, kurzeste, kurztest, kurzes
kurztz » kurtztz
kaur » kaum, kauf, kar
kaursse » kaumsse, kaufsse, karsse
kauers » kaufers, kauders, bauers

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