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

Try widening your search to All Fields.

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