Perhaps you should try some spelling variations:
presentado » presentan, presentar, presentacion, presentedo
presentamos » presentados, presentadas, presentacion, presentemos
presentaron » presentacion, presentan, presentarse, presenteron
presentation » presentacion, presentan, presentetion
presented » presente, present, presentan
presenta » presente

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

• Performing a fuzzy search may retrieve terms with similar spellings: (presentado or (presentamos or ((presentaron OR presentation) or (presented or presenta))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (presentado OR (presentamos OR ((presentaron OR presentation) OR (presented OR presenta)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentado or (presentamos or ((presentaron OR presentation) or (presented or presenta))))".
• Adding a wildcard symbol may retrieve word variants: (presentado or (presentamos or ((presentaron OR presentation) or (presented or presenta))))*.
