Perhaps you should try some spelling variations:
prestamo » prestados, prestar, presta
prestamos » prestadoss, prestars, prestas, prestados, presentamos, estamos
prestado » prestados, prestadora, estado
presentaron » presentacion, presentation, presentarse
presentan » presenta, presente, present
presentado » presenta, presented, presentar

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