Perhaps you should try some spelling variations:
massiv » massive
massiver » massiveer, massive, massiven, passiver
massiverer » massiveerer, massiveer, massivener, passiverer, massivere, massierer
passiveer » passiverer, passiver, passiviert
passiveene » passiven, passivierende
passiveand » passiven

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