• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - canh tranh va ((nhung huong) OR (nhung tuong)) ((dan than) OR (dan chan)) ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - canh tranh va ((nhung huong) OR (nhung tuong)) ((dan than) or (dan chan)) ban".
