• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) y ((nang xa) OR (nang ma)) hoi. hieu ve cam luc nhan hang vi cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) y ((nang xa) or (nang ma)) hoi. hieu ve cam luc nhan hang vi cau tren".
