Perhaps you should try some spelling variations:
presentamos » presentados, presentaron, presentadas, presentemos
presentent » presenten, presente, presentan
presenteron » presentaron, presenten, presentaran
presentado » presentan, presented, presentacion, presentedo
presentar » presentan, presentarse, presente, presenter
presenta » presente

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (presentamos or ((presentent or presenteron) or ((presentado OR presentar) or presenta)))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (presentamos OR ((presentent OR presenteron) OR ((presentado OR presentar) OR presenta)))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentamos or ((presentent or presenteron) or ((presentado OR presentar) or presenta)))*".
