Perhaps you should try some spelling variations:
"geoinformation modelle" » "geoinformation models", "information modelle", "die informationsmodelle", "geoinformation modellee", "geoinformation modele", "geoinformation modelse"
"information modell" » "information modelle", "information model", "information models"
"informatik modelle" » "information modelle", "bioinformatik modelle", "informatic model", "informatic modele", "informatic modelse", "information modellee"
"geoinformatik modelle" » "geoinformation modelle", "geobioinformatik modelle", "geoinformatic model", "geoinformatic modele", "geoinformatic modelse", "geoinformation modellee"
"informatik modell" » "informatic model", "informatic models", "information modelle"

You may be able to get more results by adjusting your search query.

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