Perhaps you should try some spelling variations:
paraboloid » parabolic
paraboloides » parabolices
paraboloideees » paraboliceees, paraboloids
paraboloide » parabolice
paraboloideeees » paraboliceeees
paraboloidal » parabolical, paraboloids, parabolica, parabolicas

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (paraboloid or (paraboloides or (((paraboloideees or (paraboloide OR parabolice)) or paraboloideeees) or paraboloidal)))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (paraboloid OR (paraboloides OR (((paraboloideees OR (paraboloide OR parabolice)) OR paraboloideeees) OR paraboloidal))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(paraboloid or (paraboloides or (((paraboloideees or (paraboloide OR parabolice)) or paraboloideeees) or paraboloidal)))".
• Adding a wildcard symbol may retrieve word variants: (paraboloid or (paraboloides or (((paraboloideees or (paraboloide OR parabolice)) or paraboloideeees) or paraboloidal)))*.
