Perhaps you should try some spelling variations:
prestamos » prestados, presentamos, estamos
presentados » presentadas, presentando, presentacion, presentas, presentans, presentars
presentaron » presentacion, presentation, presentan
presentada » presenta, presentan, presentar
presentado » presenta, presentan, presentar
presented » presente, presenta, present

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