Perhaps you should try some spelling variations:
prestamo » prestado, prestar, presta
prestamos » prestados, prestars, prestas, presentamos, estamos, prestado
prestados » presentados, prestadoras, prestadores
presentaron » presentacion, presentation, presentan, presenteron
presented » presente, present, presentan
presenta » presente

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