Perhaps you should try some spelling variations:
kur » kurz, kurt, kurs
kurtet » kurztet, kurttet, kurstet, kurten, kartet
kurtzzt » kurztzzt, kurttzzt, kurstzzt
kurtsen » kurztsen, kurttsen, kurstsen, kurtzen, kurten, kortsen
kursen » kurzsen, kurtsen, kurssen

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 ((kurtet OR kurtzzt) OR (kurtsen OR kursen))) OR kaursse).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((kur or ((kurtet or kurtzzt) or (kurtsen OR kursen))) or kaursse)".
• Adding a wildcard symbol may retrieve word variants: ((kur or ((kurtet or kurtzzt) or (kurtsen OR kursen))) or kaursse)*.
