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