Perhaps you should try some spelling variations:
presentado » presentan, presented, presentacion, presentedo, presenteado
presenta » presente, presentea
presentaron » presenteron, presentacion, presentation, presentan, presentanon, presentarseon, presenteon, presentearon
presentar » presenter, presentan, presentarse, presente, presentear
presenteado » presented, presentada, presentando, presenteeado
presenten » presente, presentan, presented, presenteen
presenter » presente, presented, presentes, presenteer
present » presente

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: (((presentado OR presenta) OR presenteado) OR ((presentaron OR (presenten OR (presentar OR presenter))) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((presentado or presenta) or presenteado) or ((presentaron or (presenten or (presentar OR presenter))) or present))~".
• Adding a wildcard symbol may retrieve word variants: (((presentado or presenta) or presenteado) or ((presentaron or (presenten or (presentar OR presenter))) or present))*.
