Perhaps you should try some spelling variations:
prestamos » prestados, estamos, prestado
presentans » presentan, presentons, presentant, presentens
presentamos » presentados, presentado, presentadas, presentemos
presentaron » presentacion, presentation, presentan, presenteron
presented » presente, present, presentan
presenta » presente

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