Perhaps you should try some spelling variations:
"informatik kulturellee" » "informatik kulturelle", "formate kultureller", "informatik aktuelle"
"informatik aktuell" » "informatik aktuelle", "informationen aktuelle", "informatik kulturelle"
"informatik modell" » "information modell", "informatic model", "informatic models"

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: (((((("informatik aktuell") OR ("informatik modell"))) OR ("informatik kulturellee"))) OR ("annotationen aktuelle"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"informatik aktuell\") OR (\"informatik modell\"))) or (\"informatik kulturellee\"))) or (\"annotationen aktuelle\"))*".
• Removing quotes may allow a broader search: (((((( informatik aktuell ) OR ( informatik modell ))) or ( informatik kulturellee ))) or ( annotationen aktuelle ))*.
