Perhaps you should try some spelling variations:
"bioinformatic modelse" » "bioinformatics models", "bioinformatik modelle", "bioinformatic modeling"
"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 ((("geoinformatik modelle") OR ("bioinformatic modelse")))).
• Removing quotes may allow a broader search: (( informatik modell ) or ((( geoinformatik modelle ) or ( bioinformatic modelse )))).
• Adding a wildcard symbol may retrieve word variants: (("informatik modell") or ((("geoinformatik modelle") or ("bioinformatic modelse"))))*.
