Perhaps you should try some spelling variations:
passiv » passive, massiv, passiver
passivierte » passiveierte, massivierte, passiverierte, passiviert, passionierte, passivseite
passiven » passiveen, massiven, passiveren, passive, passion
passiveer » passiveeer, massiveer, passivereer, passiverer, passiver, passiviert
massiven » massive, massively, massiv

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: (passiv OR ((passivierte OR massiven) OR (passiven OR passiveer))).
• Adding a wildcard symbol may retrieve word variants: (passiv or ((passivierte or massiven) or (passiven or passiveer)))*.
