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