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