Perhaps you should try some spelling variations:
massiv » massive
massivere » massiveere, massive, massives, massiger, massivee, massiee
massively » massiveely, massive
massiven » massiveen, massive, passiven
massiver » massiveer, massive, massie
passiver » passiven, passively, passiert

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 ((passive OR (massivere OR massively)) OR ((passiver OR massiven) OR massiver))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(massiv or ((passive or (massivere OR massively)) or ((passiver or massiven) or massiver)))".
• Adding a wildcard symbol may retrieve word variants: (massiv or ((passive or (massivere OR massively)) or ((passiver or massiven) or massiver)))*.
