Perhaps you should try some spelling variations:
passiv » passive, passiven, passiver
passiveierende » passiveeierende, passiveneierende, passivereierende, passivierende, passivierender, passivierenden
massiv » massive
massivere » massiveere, massiver, massive, massively

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 passiveierende) OR massiv) OR massivere).
• Adding a wildcard symbol may retrieve word variants: (((passiv or passiveierende) or massiv) or massivere)*.
