Perhaps you should try some spelling variations:
massiv » massive
massivere » massiveere, massive, massively, massiven, massivee, massivene, passivere
massiver » massiveer, massive, massiven, passiver
massiveer » massiveeer, massive, massively, massiven
passiverwerb » 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: (massiv OR (passiverwerb OR (((massivere OR massiver) OR massiveer) OR massiveer))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(massiv or (passiverwerb or (((massivere OR massiver) or massiveer) or massiveer)))".
• Adding a wildcard symbol may retrieve word variants: (massiv or (passiverwerb or (((massivere OR massiver) or massiveer) or massiveer)))*.
