Perhaps you should try some spelling variations:
prestados » presentados, prestadoras, prestadora
prestadores » prestadoras, prestadora
prestamos » presentamos, estamos, prestado
presentan » presenta, presente, present
presentaron » presentacion, presentarse, presentar
presentation » presentacion, presentado

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