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