• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ba me gioi co dong tin ) OR ( ((hoc sach) OR (hoc sinh)) nha le gioi dan dong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ba me gioi co dong tin ) or ( ((hoc sach) OR (hoc sinh)) nha le gioi dan dong tin ))*".
