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