Perhaps you should try some spelling variations:
informationen aktuelle » informationen visuelle, annotationen aktuelle, informatik aktuelle
informatik kulturelle » informatik aktuelle, informatikkultur neu, transformation kulturelle
formate kultureller » form kultureller, normalitat kultureller
"informatik aktuell" » "informatik aktuelle", "informatik modell"

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 kulturelle) OR (formate kultureller))) or (informationen aktuelle))")).
• Removing quotes may allow a broader search: (( informatik aktuell ) or ( ((((informatik kulturelle) OR (formate kultureller))) or (informationen aktuelle)) )).
• Adding a wildcard symbol may retrieve word variants: (("informatik aktuell") or ("((((informatik kulturelle) OR (formate kultureller))) or (informationen aktuelle))"))*.
