Perhaps you should try some spelling variations:
presentaban » presentan, presentada, presentadas, presentaaban
presentee » presented, presentes, presenten, presentaee
presentaron » presentacion, presentation, presentan, presentaon, presentanon, presentarseon, presentaaron
presentar » presenta, presentan, presentarse, presentaar
present » presenta
presente » presentae

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 (present OR presente)))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentaban or ((presentee or (presentaron or presentar)) or (present OR presente)))~".
• Adding a wildcard symbol may retrieve word variants: (presentaban or ((presentee or (presentaron or presentar)) or (present OR presente)))*.
