Perhaps you should try some spelling variations:
"information modell" » "information modelle", "information model", "information models"
"informatik modelle" » "information modelle", "geoinformatik modelle", "bioinformatik modelle", "informatic modelse", "information modellee", "information modelse"
"informatik modell" » "informatic models", "information modelle", "information models"
"informatic modele" » "informatic models", "information modeler", "information modelle", "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: (((((("informatik modell") OR ("informatic model"))) OR ("information modell"))) OR ((("informatik modelle") OR ("informatic modele")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"informatik modell\") OR (\"informatic model\"))) or (\"information modell\"))) or (((\"informatik modelle\") or (\"informatic modele\"))))".
• Removing quotes may allow a broader search: (((((( informatik modell ) OR ( informatic model ))) or ( information modell ))) or ((( informatik modelle ) or ( informatic modele )))).
• Adding a wildcard symbol may retrieve word variants: (((((("informatik modell") OR ("informatic model"))) or ("information modell"))) or ((("informatik modelle") or ("informatic modele"))))*.
