Perhaps you should try some spelling variations:
und liquditatsrisiko » das liquiditatsrisiko
der operationellen » der rationellen, der personellen, der redaktionellen
fur operationelle » fur rationelle, fur operations, zur operationalen
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 (der operationellen))) 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 (der operationellen))) or (((fur operationen) or (der operationen)))) risiken und liquditatsrisiko".
• Adding a wildcard symbol may retrieve word variants: modelle ((((fur operationelle) OR (der operationellen))) or (((fur operationen) or (der operationen)))) risiken und liquditatsrisiko*.
