• If you are trying to use Boolean operators, they must be ALL CAPS: (presented OR (((presentaan OR (presentadas OR presentado)) OR (presentaba OR presentaban)) OR present))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presented or (((presentaan or (presentadas or presentado)) or (presentaba OR presentaban)) or present))*".
