Perhaps you should try some spelling variations:
"informatik aktuelle" » "informationen aktuelle", "informatik kulturelle", "informationen aktuellee", "informatik kulturellee"
"informatik aktuell" » "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 aktuelle"))) OR ("informatik modell"))) OR ("informatik akademie")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"informatik aktuell\") OR (\"informatik aktuelle\"))) or (\"informatik modell\"))) or (\"informatik akademie\"))".
• Removing quotes may allow a broader search: (((((( informatik aktuell ) OR ( informatik aktuelle ))) or ( informatik modell ))) or ( informatik akademie )).
• Adding a wildcard symbol may retrieve word variants: (((((("informatik aktuell") OR ("informatik aktuelle"))) or ("informatik modell"))) or ("informatik akademie"))*.
