• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - thanh trung cua ((((nhung cong) OR (dung cong))) OR (hang nong)) manh toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - thanh trung cua ((((nhung cong) OR (dung cong))) or (hang nong)) manh toan ban*".
