Perhaps you should try some spelling variations:
presented » presente, presentan, presenteed
presenteado » presentado, presentada, presentando, presenteeado
presentaron » presentacion, presentation, presentan, presentanon, presentarseon, presenteon, presentearon, presenteron
presenteen » presentesen, presenten, presentee, presenteeen
presentar » presentan, presentarse, presente, presentear, presenter
present » presente
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: ((presented OR presenteado) OR ((presentaron OR (presenteen OR presentar)) OR (present OR presenta)))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((presented or presenteado) or ((presentaron or (presenteen or presentar)) or (present OR presenta)))~".
• Adding a wildcard symbol may retrieve word variants: ((presented or presenteado) or ((presentaron or (presenteen or presentar)) or (present OR presenta)))*.
