• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - manh hung cua ((nhung cong) OR (thong cong)) ((dan than) OR (van than)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - manh hung cua ((nhung cong) OR (thong cong)) ((dan than) or (van than)) cau*".
