Perhaps you should try some spelling variations:
presented » presente, presentan, presenteed
presenteado » presentado, presentada, presentando, presenteeado
presentaron » presentacion, presentation, presentan, presenteron, presentearon
presenten » presente, presentan, presentes, presenteen
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 presenta)) OR present))~.
• Adding a wildcard symbol may retrieve word variants: ((presented or presenteado) or ((presentaron or (presenten or presenta)) or present))*.
