Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passiviert » passiveiert, massiviert, passiveniert, passioniert, passivieren, passiert
passiveene » passiveeene, massiveene, passiveneene, passiven, passivierende
passiveand » passiveeand, massiveand, passiveneand, passiven
massiver » massive, massiven, passiver
massiverer » massiveer, massivener, passiverer, massivere, massierer

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 ((passiviert OR massiver) OR massiverer)) OR (passiveene OR passiveand)).
• Adding a wildcard symbol may retrieve word variants: ((passiv or ((passiviert or massiver) or massiverer)) or (passiveene or passiveand))*.
