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