Perhaps you should try some spelling variations:
massiv » massive
massiverer » massiveerer, massivere, massierer, passiverer
passivieren » passivierende, passivierung, passieren
passively » massively, passive, passivity

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 (passivieren OR (massiverer OR passively)))*.
