Perhaps you should try some spelling variations:
prestamos » prestados, presentamos, estamos
presentans » presentan, presentons, presentant, presentens
presentado » presentan, presentar, presentacion, presentedo
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 (presentado OR presentaron)) OR (presented OR presenta)))~.
• Adding a wildcard symbol may retrieve word variants: (prestamos or ((presentans or (presentado or presentaron)) or (presented or presenta)))*.
