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