Perhaps you should try some spelling variations:
presentado » presenta, presentan, presented, presentaado
present » presenta
presentaron » presentaaron, presentacion, presentation, presentan, presentaon, presentanon, presentarseon
presentane » presentaane, presentan, presentare, presentant
presentar » presentaar, presenta, presentan, presentarse
presente » presentae

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 present) OR ((presentaron OR (presentane OR presentar)) OR presente))~.
• Adding a wildcard symbol may retrieve word variants: ((presentado or present) or ((presentaron or (presentane or presentar)) or presente))*.
