Perhaps you should try some spelling variations:
passiver » passive, passively, passiert
passiven » passive, passion
passiveneneand » passiveeneand, passioneneand
massiver » massive, massiven, massively
passiveer » passiverer, passiviert, passive
passivierende » passivierender, passivieren, aktivierende

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: ((passiver OR ((passiven OR massiver) OR passiveer)) OR (passivierende OR passiveneneand)).
• Adding a wildcard symbol may retrieve word variants: ((passiver or ((passiven or massiver) or passiveer)) or (passivierende or passiveneneand))*.
