Perhaps you should try some spelling variations:
informationen anteil » informationen teil, informationen intern, informationen unter
informatik aktuelle » informationen aktuelle, informatik kulturelle
"information modell" » "information modelle", "information model", "information models"
"informatik modell" » "informatic model", "informatic models", "information modelle"

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