Perhaps you should try some spelling variations:
presentado » presenta, presented, presentacion
presenteado » presented, presentada, presentando
presentaron » presentacion, presentation, presentarse, presentaon, presentarseon, presenton
presenten » presented, presentes, presenting
presentar » presenta, presentarse, present
presentan » presenta, present, presentacion

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