Perhaps you should try some spelling variations:
presentan » presenta, presentacion, presentaan
presentes » presented, presents, presenta, presentaes
presentaron » presentacion, presentarse, presentar, presentaaron
presentation » presentacion, presentaation
presentaaar » presentar, presentada, presentadas, presentaaaar
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: (presentan or ((presentes or ((presentaron OR presentation) or (presentaaar or presente))) or present))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (presentan OR ((presentes OR ((presentaron OR presentation) OR (presentaaar OR presente))) OR present))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentan or ((presentes or ((presentaron OR presentation) or (presentaaar or presente))) or present))*".
