Perhaps you should try some spelling variations:
presentado » presented, presentacion, presentation, presentedo, presenteado
presentar » presentarse, presente, presented, presenter, presentear
presenta » presente, presentea
presentan » presenten, presente, presentacion, presentean
presenteeed » presented, presentee, presentees, presenteeeed
presenten » presente, presented, presentes, presenteen
present » 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 presentar) or (((presenta or presenteeed) or (presentan OR presenten)) or present))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((presentado OR presentar) OR (((presenta OR presenteeed) OR (presentan OR presenten)) OR present))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((presentado or presentar) or (((presenta or presenteeed) or (presentan OR presenten)) or present))*".
