Perhaps you should try some spelling variations:
presentan » presenta, presente, presentacion, presentean, presentaan
presentee » presente, presented, presentes, presenteee, presentaee
presentaban » presentaron, presentada, presentadas, presenteaban, presentaaban
presentaer » presenter, presentador, presentasen, presenteaer, presentaaer
presentar » presenta, presentarse, presente, presentear, presentaar
present » presente, 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 ((presentee or (presentaban or (presentaer OR presentar))) or present))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (presentan OR ((presentee OR (presentaban OR (presentaer OR presentar))) OR present))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentan or ((presentee or (presentaban or (presentaer OR presentar))) or present))*".
