Perhaps you should try some spelling variations:
paraboloid » paraboloide, paraboloides, parabolic
paraboloideseees » paraboloideeseees, paraboloideseseees, paraboliceseees, paraboloides
paraboloideal » paraboloideeal, paraboloideseal, paraboliceal, paraboloidal, paraboloide, paraboloides
paraboloideseal » paraboloideeseal, paraboloideseseal, paraboliceseal, paraboloides, paraboloidal
paraboloids » paraboloides, paraboloidess, parabolics

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: (paraboloid OR (parabolices OR (paraboloideseees OR ((paraboloideal OR paraboloideseal) OR paraboloids))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(paraboloid or (parabolices or (paraboloideseees or ((paraboloideal OR paraboloideseal) or paraboloids))))~".
• Adding a wildcard symbol may retrieve word variants: (paraboloid or (parabolices or (paraboloideseees or ((paraboloideal OR paraboloideseal) or paraboloids))))*.
