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