Perhaps you should try some spelling variations:
presentaban » presentaron, presentada, presentadas, presenteaban, presenteban
presentaen » presentasen, presenten, presentaun, presenteaen, presenteen
presentaaan » presentaran, presentarian, presentaron, presenteaaan, presenteaan
presentan » presente, presentacion, presentean, presenten
presentar » presentarse, presente, presented, presentear, presenter
present » presente
presenta » presentea, 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: (presentaban OR ((presentaen OR ((presentaaan OR presentan) OR presentar)) OR (present OR presenta)))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentaban or ((presentaen or ((presentaaan or presentan) or presentar)) or (present OR presenta)))~".
• Adding a wildcard symbol may retrieve word variants: (presentaban or ((presentaen or ((presentaaan or presentan) or presentar)) or (present OR presenta)))*.
