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

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