Perhaps you should try some spelling variations:
prestamos » prestados, presentamos, estamos
presentados » presentada, presentando, presentacion, presentas, presentans, presentars
presentadas » presentada
presentaron » presentacion, presentation, presentan
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 (presentadas OR presentaron)) OR (presentado OR presented)))~.
• Adding a wildcard symbol may retrieve word variants: (prestamos or ((presentados or (presentadas or presentaron)) or (presentado or presented)))*.
