Perhaps you should try some spelling variations:
passiv » passive, passiven, passiver
passivierungr » passiveierungr, passivenierungr, passiverierungr, passivierung, passivierungs, passivierender
massiv » massive
massiven » massiveen, massive, passiven, massively
massiveierende » massiveeierende, 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 massiv) OR (massiven OR massiveierende)) OR passivierungr).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((passiv OR massiv) or (massiven or massiveierende)) or passivierungr)".
• Adding a wildcard symbol may retrieve word variants: (((passiv OR massiv) or (massiven or massiveierende)) or passivierungr)*.
