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

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