Perhaps you should try some spelling variations:
presentado » presented, presentacion, presentedo, presenteado
presenta » presente, presentea
presentan » presenten, presente, presentacion, presentean
presentada » presenteda, presented, presenteada
presentar » presenter, presentarse, presente, presented, presentear
presentaea » presenteea, presentara, presentaba, presentata, presenteaea
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 (((presentan OR (presentada OR presentar)) OR presentaea) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((presentado or presenta) or (((presentan or (presentada OR presentar)) or presentaea) or present))~".
• Adding a wildcard symbol may retrieve word variants: ((presentado or presenta) or (((presentan or (presentada OR presentar)) or presentaea) or present))*.
