Perhaps you should try some spelling variations:
prestado » prestados, prestadora, estado
presentado » presentan, presented, presentedo
presentaron » presentation, presentan, presentarse, presentanon, presentarseon, presenteon, presenteron
presentaare » presentare, presentarse, presentara, presenteare
presentar » presentan, presentarse, presente, presenter
presentacion » presentecion
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: ((prestado OR presentado) OR (((presentaron OR presentacion) OR (presentaare OR presentar)) OR presenta))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((prestado or presentado) or (((presentaron OR presentacion) or (presentaare or presentar)) or presenta))~".
• Adding a wildcard symbol may retrieve word variants: ((prestado or presentado) or (((presentaron OR presentacion) or (presentaare or presentar)) or presenta))*.
