Perhaps you should try some spelling variations:
"bioinformatik modelle" » "geoinformatik modelle", "bioinformatic modeling", "bioinformatics models", "bioinformation modelle", "biogeoinformatik modelle", "bioinformatic model", "bioinformatic modele", "bioinformatic modelse"
"bioinformatic modele" » "bioinformatics models", "bioinformatics model", "bioinformatic modeling"
"informatik modelle" » "information modelle", "geoinformatik modelle", "informatic model", "informatic modele", "informatic modelse"
"informatik modell" » "information modell", "informatic model", "informatic 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 ((("informatik modelle") OR ((("bioinformatik modelle") OR ("bioinformatic modele")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"informatik modell\") or (((\"informatik modelle\") or (((\"bioinformatik modelle\") OR (\"bioinformatic modele\"))))))".
• Removing quotes may allow a broader search: (( informatik modell ) or ((( informatik modelle ) or ((( bioinformatik modelle ) OR ( bioinformatic modele )))))).
• Adding a wildcard symbol may retrieve word variants: (("informatik modell") or ((("informatik modelle") or ((("bioinformatik modelle") OR ("bioinformatic modele"))))))*.
