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

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: modell ((((fur operationelle) OR (der operationellen))) OR (der operationen)) risiken und liquditatsrisiko.
• Adding a wildcard symbol may retrieve word variants: modell ((((fur operationelle) or (der operationellen))) or (der operationen)) risiken und liquditatsrisiko*.
