Perhaps you should try some spelling variations:
massiv » massive
massiveere » massiveeere, massivere
massiven » massiveen, massive, passiven, massively
massiveen » massiveeen, massivement, massivsten, massigeren
massiver » massiveer, massive, massively, 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 massiveere) OR ((passiver OR (massiven OR massiveen)) OR massiver))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(massiv or ((passive or massiveere) or ((passiver or (massiven OR massiveen)) or massiver)))".
• Adding a wildcard symbol may retrieve word variants: (massiv or ((passive or massiveere) or ((passiver or (massiven OR massiveen)) or massiver)))*.
