Perhaps you should try some spelling variations:
presentaban » presentan, presentada, presentadas, presenteaban, presentaaban
presentee » presente, presented, presentes, presenteee, presentaee
presentaron » presentacion, presentation, presentan, presentaon, presentanon, presentarseon, presentearon, presentaaron
presentar » presenta, presentan, presentarse, presentear, presentaar
presentaar » presentadas, presentaran, presentador, 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: (presentaban OR ((presentee OR (presentaron OR (presentar OR presentaar))) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentaban or ((presentee or (presentaron or (presentar OR presentaar))) or present))~".
• Adding a wildcard symbol may retrieve word variants: (presentaban or ((presentee or (presentaron or (presentar OR presentaar))) or present))*.
