Perhaps you should try some spelling variations:
informationen aktuelle » informationen visuelle, annotationen aktuelle, informationen anteil
informatik aktuelle » informatik kulturelle, informatik akademie
"informatik aktuell" » "informatik modell", "informatik kulturelle"
"informatic model" » "informatic models", "information model", "informative model"

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