Perhaps you should try some spelling variations:
presented » presente, presenteed
presenta » presente, presentea
presentan » presenten, presente, presentacion, presentean
presentar » presenter, presentarse, presente, presents, presentear
presentae » presentee, presentare, presentase, presente, presenteae
presentanse » presentense, presentese, presentacionse, presentarse, presentase, presentandose, presenteanse
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: ((presented OR presenta) OR (((presentan OR (presentar OR presentae)) OR presentanse) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((presented OR presenta) or (((presentan or (presentar or presentae)) or presentanse) or present))~".
• Adding a wildcard symbol may retrieve word variants: ((presented OR presenta) or (((presentan or (presentar or presentae)) or presentanse) or present))*.
