Perhaps you should try some spelling variations:
presentamos » presentado, presentadas, presentacion, presenteamos, presentaamos
presentados » presentado, presentadas, presentada, presenteados, presentaados
presentaron » presentacion, presentation, presentarse, presentearon, presentaaron
presentan » presenta, presente, presentacion, presentean, presentaan
presentae » presentare, presentase, presente, presenteae, presentaae
present » presente, presenta

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: (presentamos OR ((presentados OR (presentaron OR presentan)) OR (presentae OR present)))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentamos or ((presentados or (presentaron OR presentan)) or (presentae or present)))~".
• Adding a wildcard symbol may retrieve word variants: (presentamos or ((presentados or (presentaron OR presentan)) or (presentae or present)))*.
