Perhaps you should try some spelling variations:
massiv » massive
massivieren » massiveieren, passivieren, massivere, passivierung
massigeren » massigen, massivere, massierer, massingeren, massiveen, massieen
massiger » massinger, massive, massie
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 (massivieren OR ((massigeren OR massiger) OR passivierende)))*.
