Perhaps you should try some spelling variations:
"information modell" » "information modelle", "information model", "information models"
"informatik modell" » "informatic model", "informatic models", "information modelle"
"informatic modele" » "informatic model", "informatic models", "information modeler"

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 modell") OR ("information modell"))) OR ("informatic modele")).
• Removing quotes may allow a broader search: (((( informatik modell ) or ( information modell ))) or ( informatic modele )).
• Adding a wildcard symbol may retrieve word variants: (((("informatik modell") or ("information modell"))) or ("informatic modele"))*.
