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

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