Perhaps you should try some spelling variations:
presented » presente, presenta, presentan, presenteed, presentaed
presentando » presentado, presentan, presentada, presenteando, presentaando
presentaron » presentacion, presentation, presentan, presentearon, presentaaron
presenten » presente, presentan, presentes, presenteen, presentaen
presentear » presentar, presenter, presente, presenteear, presentaear
present » presente, presenta

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((presented OR presentando) OR ((presentaron OR (presenten OR presentear)) OR present))~".
• Adding a wildcard symbol may retrieve word variants: ((presented OR presentando) OR ((presentaron OR (presenten OR presentear)) OR present))*.
