• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((thuc hanh) OR (chieu sach)) - hanh mang va ((nhung huong) OR (nhung cong)) dan thanh ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((thuc hanh) or (chieu sach)) - hanh mang va ((nhung huong) OR (nhung cong)) dan thanh ban*".
