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