• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) cho hang x hoi. hieu ((ve chao) OR (ve cham)) xu va dinh van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) cho hang x hoi. hieu ((ve chao) OR (ve cham)) xu va dinh van cua tre*".
