Perhaps you should try some spelling variations:
"bioinformatics medical" » "bioinformatics biomedical", "bioinformatics methods", "bioinformatics models"
"bioinformatics model" » "bioinformatics models", "bioinformatics based", "bioinformatics molecular"
"geoinformatic model" » "geoinformatik modelle", "geoinformation models", "informatic model"
"informatik modelle" » "information modelle", "geoinformatik modelle", "bioinformatik modelle", "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 ((("geoinformatic model") OR ((("bioinformatics model") OR ("bioinformatics medical")))))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"informatik modell\") or (((\"informatik modelle\") or (((\"geoinformatic model\") or (((\"bioinformatics model\") OR (\"bioinformatics medical\"))))))))".
• Removing quotes may allow a broader search: (( informatik modell ) or ((( informatik modelle ) or ((( geoinformatic model ) or ((( bioinformatics model ) OR ( bioinformatics medical )))))))).
• Adding a wildcard symbol may retrieve word variants: (("informatik modell") or ((("informatik modelle") or ((("geoinformatic model") or ((("bioinformatics model") OR ("bioinformatics medical"))))))))*.
