• Performing a fuzzy search may retrieve terms with similar spellings: (estamos or (((presentados or (presentaron OR presentation)) or (presentaran or presentan)) or (present or presenta)))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (estamos OR (((presentados OR (presentaron OR presentation)) OR (presentaran OR presentan)) OR (present OR presenta)))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(estamos or (((presentados or (presentaron OR presentation)) or (presentaran or presentan)) or (present or presenta)))*".
