• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - ((hanh trang) OR (canh tranh)) ((cua dung) OR (qua dung)) trong ban than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - ((hanh trang) or (canh tranh)) ((cua dung) OR (qua dung)) trong ban than cap*".
