• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) sach - hanh trang ((tan dung) OR (tran dung)) cong san tan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) sach - hanh trang ((tan dung) OR (tran dung)) cong san tan cau*".
