Perhaps you should try some spelling variations:
und liquditatsrisiko » das liquiditatsrisiko
fur operationelle » der operationellen, fur rationelle, fur operations
fur operationen » fur kooperationen, fur operations
der operationen » der operativen, der operation, der operatoren
modelle » modell

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: modelle ((fur operationelle) OR (((fur operationen) OR (der operationen)))) risiken und liquditatsrisiko.
• The words AND, OR and NOT may confuse the search; try adding quotes: "modelle ((fur operationelle) or (((fur operationen) OR (der operationen)))) risiken und liquditatsrisiko".
• Adding a wildcard symbol may retrieve word variants: modelle ((fur operationelle) or (((fur operationen) OR (der operationen)))) risiken und liquditatsrisiko*.
