Perhaps you should try some spelling variations:
presentado » presentan, presented, presentacion, presentedo, presenteado
presenta » presente, presentea
presentar » presenter, presentan, presentarse, presente, presentear
presenteron » presentaron, presenten, presentaran, presenteeron
presentedans » presentadas, presentedin, presentan, presenteedans
present » 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: ((presentado OR presenta) OR ((presenteron OR (presentedans OR presentar)) OR present))~.
• Adding a wildcard symbol may retrieve word variants: ((presentado or presenta) or ((presenteron or (presentedans or presentar)) or present))*.
