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