Perhaps you should try some spelling variations:
prestados » presentados, prestadoras, prestadores
presentaation » presentation, presentacion, presentations, presenteation
presentes » presente, presented, presents
presentan » presente, present, presentacion, presenten
presentar » presentarse, presente, present, presenter
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: (prestados OR ((presentaation OR ((presentes OR presentan) OR presentar)) OR presenta))~.
• Adding a wildcard symbol may retrieve word variants: (prestados or ((presentaation or ((presentes or presentan) or presentar)) or presenta))*.
