• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach bai me gioi con dong tin ) OR ( thu ((sach ha) OR (sach xa)) le gioi can luong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach bai me gioi con dong tin ) or ( thu ((sach ha) OR (sach xa)) le gioi can luong tin ))".
