Perhaps you should try some spelling variations:
massiv » massive
massiverer » massiveerer, massivere, massierer, massiver
massiveer » massiveeer, massiver, massive, massively
passiverer » passiverwerb, passivieren, passiver
massferrer » masferrer, massfehler, massfeller

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 (passiverer OR ((massiverer OR massferrer) OR massiveer)))*.
