Perhaps you should try some spelling variations:
passiv » passive, passiven, passiver
passiveierende » passiveeierende, passiveneierende, passivereierende, passivierende, passivierender, passivieren
passivierenden » passiveierenden, passivenierenden, passiverierenden, passivierende, passivierender, aktivierenden
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 passivierenden)) OR massiv) OR massivere).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((passiv or (passiveierende OR passivierenden)) or massiv) or massivere)".
• Adding a wildcard symbol may retrieve word variants: (((passiv or (passiveierende OR passivierenden)) or massiv) or massivere)*.
