Perhaps you should try some spelling variations:
presenteado » presentado, presentada, presentando, presenteeado, presentaeado
presented » presente, presenta, presentan, presenteed, presentaed
presentaron » presentacion, presentation, presentan, presentaon, presentanon, presentarseon, presentearon, presentaaron
presentane » presentan, presentare, presentant, presenteane, presentaane
presentar » presenta, presentan, presentarse, presentear, presentaar
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: ((presenteado OR presented) OR ((presentaron OR (presentane OR presentar)) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((presenteado OR presented) or ((presentaron or (presentane or presentar)) or present))~".
• Adding a wildcard symbol may retrieve word variants: ((presenteado OR presented) or ((presentaron or (presentane or presentar)) or present))*.
