Perhaps you should try some spelling variations:
presentaron » presentacion, presentation, presentan, presenteron, presentanon, presentarseon, presenteon, presentearon
presentasen » presentase, presentesen, presentadoen, presenteasen
presentaaan » presentaban, presentaran, presentarian, presenteaan, presenteaaan
presenta » presente, presentea
presentar » presenter, presentan, presentarse, presente, presentear
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: (presentaron OR ((presentasen OR ((presentaaan OR presenta) OR presentar)) OR present))~.
• Adding a wildcard symbol may retrieve word variants: (presentaron or ((presentasen or ((presentaaan or presenta) or presentar)) or present))*.
