Perhaps you should try some spelling variations:
prestamo » prestamos, prestado, prestados
prestadoss » prestados, prestadoras, prestadores
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 (prestadoss OR (presentaron OR ((presentedo OR presentando) OR presenta))))~.
• Adding a wildcard symbol may retrieve word variants: (prestamo or (prestadoss or (presentaron or ((presentedo or presentando) or presenta))))*.
