Perhaps you should try some spelling variations:
informatik modelle » information modelle, geoinformatik modelle, bioinformatik modelle
informatic models » information models, informative models, information modell
informatik modell » information modell, information modelle, information models
informatic model » information model, informative model, information models

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