Perhaps you should try some spelling variations:
massiv » massive
massiveere » massiveeere, massivere, massiver
passiverer » passiverwerb, passivieren, passagerer, passiveer, passivener, passivelyer
passieren » passiert, passiven
passiver » passive, passiven, passively

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 passieren) OR (massiveere OR passiver)))*.
