Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passiveieren » passiveeieren, massiveieren, passiveneieren, passivieren, passionierten, passivierende
passivenierung » passiveenierung, massivenierung, passivenenierung, passivierung, passivierungs
massiven » massive, passiven, massiv
massively » massive
massivieren » passivieren, massivere, massigeren

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 ((passiveieren OR passivenierung) OR massivieren))).
• Adding a wildcard symbol may retrieve word variants: (passiv or ((massiven or massively) or ((passiveieren or passivenierung) or massivieren)))*.
