Perhaps you should try some spelling variations:
informationen aktuelle » informationen visuelle, annotationen aktuelle, informatik aktuelle
informatik kulturelle » informatik aktuelle, formate kultureller, informatikkultur neu
"informatik aktuell" » "informatik aktuelle", "informatik modell"
"informatic models" » "informatic model", "information models", "informative 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 ("informatic models"))) OR ("((informatik kulturelle) or (informationen aktuelle))")).
• Removing quotes may allow a broader search: (((( informatik aktuell ) or ( informatic models ))) or ( ((informatik kulturelle) or (informationen aktuelle)) )).
• Adding a wildcard symbol may retrieve word variants: (((("informatik aktuell") or ("informatic models"))) or ("((informatik kulturelle) or (informationen aktuelle))"))*.
