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