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

Try widening your search to All Fields.

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