Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passivierung » passiveierung, massivierung, passivenierung, aktivierung
massivieren » passivieren, massigeren, passivierende
massivierung » passivierungs, massierung, aktivierung
massiveren » massigeren, massivement, passivieren, massivern, massiven, massivelyn
massivere » massiver, massive, massively

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: (passiv OR ((massivieren OR (passivierung OR massivierung)) OR (massiveren OR massivere))).
• Adding a wildcard symbol may retrieve word variants: (passiv or ((massivieren or (passivierung or massivierung)) or (massiveren or massivere)))*.
