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
presentedans » presentadas, presentedin, presentan, presenteedans
presentear » presenter, presente, presentan, presenteear
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 ((presentaron OR (presentedans OR (presentar OR presentear))) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((presentado or presenta) or ((presentaron or (presentedans or (presentar OR presentear))) or present))~".
• Adding a wildcard symbol may retrieve word variants: ((presentado or presenta) or ((presentaron or (presentedans or (presentar OR presentear))) or present))*.
