Perhaps you should try some spelling variations:
kur » kurt, kurs, kaur
kurz » kurtz, kursz, kaurz
kurtz » kurttz, kurstz, kaurtz, kurt
kurze » kurtze, kursze, kaurze
kurzest » kurtzest, kurszest, kaurzest, kurzeste, kurztest, kurzes
horst » host, horse

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