Perhaps you should try some spelling variations:
massiv » massive
massivieren » massiveieren, passivieren, massivere, massigeren
massiveren » massiveeren, massivere, massigeren, massivement
massiveeren » massiveeeren, massivere, passivieren, massigeren
passivierung » aktivierung

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 passivierung) OR (massiveren OR massiveeren))).
• Adding a wildcard symbol may retrieve word variants: (massiv or ((massivieren or passivierung) or (massiveren or massiveeren)))*.
