Perhaps you should try some spelling variations:
prestamos » prestados, presentamos, estamos
presenteron » presentaron, presenten, presentaran, presenteeron
presentado » presentan, presented, presentar, presenteado, presentedo
presenteado » presented, presentada, presentando, presenteeado
present » presente
presenta » presentea, presente

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (prestamos or ((presenteron or (presentado OR presenteado)) or (present or presenta)))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (prestamos OR ((presenteron OR (presentado OR presenteado)) OR (present OR presenta))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(prestamos or ((presenteron or (presentado OR presenteado)) or (present or presenta)))".
• Adding a wildcard symbol may retrieve word variants: (prestamos or ((presenteron or (presentado OR presenteado)) or (present or presenta)))*.
