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