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