• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - hanh trang cua ((((nhung duong) OR (nhung dung))) OR (nhung huong)) manh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - hanh trang cua ((((nhung duong) OR (nhung dung))) or (nhung huong)) manh toan cau*".
