Perhaps you should try some spelling variations:
presented » presente, presenta, presenteed, presentaed
presentan » presenta, presente, presentacion, presentean, presentaan
presentanse » presentase, presentese, presentacionse, presentandose, presentantes, presenteanse, presentaanse
presentar » presenta, presente, presents, presentear, presentaar
presentarse » presentase, presentese, presentsse, presentearse, presentaarse
presentae » presentare, presentase, presente, presenteae, presentaae
present » presente, presenta

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 (((presentan OR ((presentar OR presentarse) OR presentae)) OR presentanse) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presented or (((presentan or ((presentar OR presentarse) or presentae)) or presentanse) or present))~".
• Adding a wildcard symbol may retrieve word variants: (presented or (((presentan or ((presentar OR presentarse) or presentae)) or presentanse) or present))*.
