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