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