Perhaps you should try some spelling variations:
passively » massively, passivity, passiven
passivere » passiverer, massivere, passivieren, passivene, passierte
passiverely » passivererly, massiverely, passivierenly, passivenely, passiertely, passiverer
passiver » passiven, passiert
passiverwerb » passivenwerb, passiertwerb, passiverer
massiv » 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: ((passively OR ((passive OR (passivere OR passiver)) OR (passiverely OR passiverwerb))) OR massiv).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((passively or ((passive or (passivere OR passiver)) or (passiverely or passiverwerb))) or massiv)".
• Adding a wildcard symbol may retrieve word variants: ((passively or ((passive or (passivere OR passiver)) or (passiverely or passiverwerb))) or massiv)*.
