Perhaps you should try some spelling variations:
massiv » massive
massivere » massiveere, massiver, massive, massively
passiveeere » passiverer, passiverwerb, passiveere, passivenere, passiverere
passiveen » passiven, passivieren, passiveand, passivenn, passivern
passivee » passive, passiven, passiver

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: (((massiv OR (massivere OR passiveeere)) OR passiveen) OR passivee).
• Adding a wildcard symbol may retrieve word variants: (((massiv or (massivere or passiveeere)) or passiveen) or passivee)*.
