Perhaps you should try some spelling variations:
passiv » passive, massiv, passiver
passivierender » passiveierender, massivierender, passiverierender, passivierende, aktivierender, passivierendeder, passivierungder, passierender
passivieren » passiveieren, massivieren, passiverieren, passivierende, passivierung, passieren
passiven » passiveen, massiven, passiveren, passive, passion
massiver » massive, massiven, passiver

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 ((passivierender OR (passivieren OR passiven)) OR massiver))*.
