Perhaps you should try some spelling variations:
prestamo » prestado, prestados, prestar
prestamos » prestados, prestadoss, prestars, presentamos, estamos
presentaron » presentacion, presentation, presentan, presenteron
presentedo » presented, presentado, presentados
presentando » presentado, presentan, presentada, presentendo
presenta » 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 (prestamos OR (presentaron OR ((presentedo OR presentando) OR presenta))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(prestamo or (prestamos or (presentaron or ((presentedo OR presentando) or presenta))))~".
• Adding a wildcard symbol may retrieve word variants: (prestamo or (prestamos or (presentaron or ((presentedo OR presentando) or presenta))))*.
