Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passivierungr » passiveierungr, massivierungr, passivenierungr, passivierung, passivierungs, passivierender
massiven » massive, passiven, massiv
massively » massive
massivierende » passivierende, passivierender, passivierenden

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 ((massiven OR massively) OR massivierende)) OR passivierungr).
• Adding a wildcard symbol may retrieve word variants: ((passiv or ((massiven or massively) or massivierende)) or passivierungr)*.
