Perhaps you should try some spelling variations:
prestamo » prestamos, prestado, prestados
presentar » presentarse, presente, presented, presentear, presenter
presentaron » presentarseon, presenteon, presentedon, presentacion, presentation, presentarse, presentearon, presenteron
presentan » presente, presentacion, presentean, presenten
present » presente
presenta » presentea, presente

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