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