Perhaps you should try some spelling variations:
prestamo » prestamos, prestado, prestar
prestados » presentados, prestadoras, prestadores
presentaron » presentacion, presentan, presentarse, presenteron
presentation » presentacion, presentan, presentado, presentetion
presenta » presente
presented » presente, present, presentan

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (prestamo or ((prestados or ((presentaron OR presentation) or presenta)) or presented))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (prestamo OR ((prestados OR ((presentaron OR presentation) OR presenta)) OR presented)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(prestamo or ((prestados or ((presentaron OR presentation) or presenta)) or presented))".
• Adding a wildcard symbol may retrieve word variants: (prestamo or ((prestados or ((presentaron OR presentation) or presenta)) or presented))*.
