Perhaps you should try some spelling variations:
presentado » presentar, presentacion, presentation, presenteado, presentedo
presented » presente, presenteed
presentan » presente, presentacion, presentean, presenten
present » presente
presenten » presenteen, presente, presentes, presenting
presentarse » presentearse, presenterse
presenta » presentea, 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 presented) OR (((presentan OR present) OR (presenten OR presentarse)) OR presenta))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((presentado or presented) or (((presentan OR present) or (presenten or presentarse)) or presenta))~".
• Adding a wildcard symbol may retrieve word variants: ((presentado or presented) or (((presentan OR present) or (presenten or presentarse)) or presenta))*.
