Perhaps you should try some spelling variations:
passiv » passive, passiven, passiver
passivene » passiveene, passivenene, passiverene, passiven, passiveand, passiverer
passivierende » passiveierende, passivenierende, passiverierende, passivierender, passivieren, aktivierende
massiv » massive
massiverer » massiveerer, massivere, massierer, passiverer

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