Perhaps you should try some spelling variations:
das liquiditatsrisiko » von liquiditatsrisiken
operationen risiken » operationellen risiken, operationelle risiken, operationaler risiken
fur operationen » fur kooperationen, der operationen, fur operations

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