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