Perhaps you should try some spelling variations:
"geoinformation modelle" » "geoinformation models", "information modelle", "die informationsmodelle"
"information models" » "information model", "information modeling", "information modelling"
"informatik modelle" » "informatik modell", "information modelle", "bioinformatik modelle"
"geoinformatik modelle" » "geoinformatik modell", "geoinformation modelle", "geobioinformatik modelle"
"informatic models" » "informatic model", "informative models", "informatik modell"

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: "((((\"informatic models\") OR (\"information models\"))) OR (((\"informatik modelle\") OR (((\"geoinformatik modelle\") OR (\"geoinformation modelle\"))))))".
• Removing quotes may allow a broader search: (((( informatic models ) OR ( information models ))) OR ((( informatik modelle ) OR ((( geoinformatik modelle ) OR ( geoinformation modelle )))))).
• Adding a wildcard symbol may retrieve word variants: (((("informatic models") OR ("information models"))) OR ((("informatik modelle") OR ((("geoinformatik modelle") OR ("geoinformation modelle"))))))*.
