Perhaps you should try some spelling variations:
presentado » presenta, presented, presentar, presentaado
presentaron » presentacion, presentation, presentar, presentaaron
presentan » presenta, presentacion, presentaan
presentase » presentare, presentas, presentarle, presentaase
presentarse » presentaarse
presente » presentae
present » presenta

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

• Performing a fuzzy search may retrieve terms with similar spellings: (presentado or (((presentaron or presentan) or ((presentase OR presentarse) or presente)) or present))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (presentado OR (((presentaron OR presentan) OR ((presentase OR presentarse) OR presente)) OR present))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentado or (((presentaron or presentan) or ((presentase OR presentarse) or presente)) or present))*".
