Perhaps you should try some spelling variations:
"information modelle" » "information model", "information modeler", "information module", "information modele", "information modelere", "information modee"
"information modell" » "information model", "information modeler", "information mode"
"information models" » "information model", "information modeling", "information modelling"
"informatik modell" » "informatic model", "informatic models", "informative models"

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