Perhaps you should try some spelling variations:
massiv » massive
massiven » massiveen, massive, passiven, massively
massivierungr » massiveierungr, passivierung, passivierungs, massierung
passivierende » passivierender, passivieren, aktivierende

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 (massiven OR passivierende)) OR massivierungr).
• Adding a wildcard symbol may retrieve word variants: ((massiv or (massiven or passivierende)) or massivierungr)*.
