Perhaps you should try some spelling variations:
passiv » passive, passiven, passiver
passivieren » passiveieren, passivenieren, passiverieren, passivierung, passieren, passagieren
passivierende » passiveierende, passivenierende, passiverierende, passivierungde, passierende, passagierende, passivierender, passivierung, passerende
passiveierungr » passiveeierungr, passiveneierungr, passivereierungr, passivierung, passivierungs
massiv » massive
aktivierende » aktivierenden, aktivieren, motivierende

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