Perhaps you should try some spelling variations:
"bioinformatik modelle" » "bioinformatic modeling", "bioinformatics models", "bioinformatics model", "bioinformation modelle", "bioinformatic model", "bioinformation modell", "bioinformatic modele", "bioinformation modellee"
"informatik modelle" » "information modelle", "informatic model", "information modell", "informatic modele", "information modellee"
"geoinformatik modelle" » "geoinformation modelle", "geoinformatic model", "geoinformation modell", "geoinformatic modele", "geoinformation modellee"
"informatik modell" » "information modell", "informatic model", "information modelle"
"informatic models" » "informatic model", "information models", "informative models"

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