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

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: (("informatic model") OR ((("information modelse") OR ("informatik modell")))).
• Removing quotes may allow a broader search: (( informatic model ) or ((( information modelse ) or ( informatik modell )))).
• Adding a wildcard symbol may retrieve word variants: (("informatic model") or ((("information modelse") or ("informatik modell"))))*.
