Perhaps you should try some spelling variations:
passiv » passive, passiven, passiver
passiveieren » passiveeieren, passiveneieren, passivereieren, passivieren, passionierten, passivierende
passivierenden » passiveierenden, passivenierenden, passiverierenden, passivierende, passivierender, aktivierenden
massiven » massive, passiven, massiveen
massiv » massive
massively » massiveely, massive

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 massiv) OR massively) OR (passiveieren OR passivierenden))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(passiv or (((massiven OR massiv) or massively) or (passiveieren or passivierenden)))".
• Adding a wildcard symbol may retrieve word variants: (passiv or (((massiven OR massiv) or massively) or (passiveieren or passivierenden)))*.
