Perhaps you should try some spelling variations:
prestamo » prestamos, prestado, prestados
presentamos » presentados, presentado, presentadas
presentaron » presentacion, presentation, presentarse
presentan » presenta, presente, present
presentas » presentase, presenta, presents
presented » presente, presenta, present

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