• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((anh tang) OR (nhan dang)) cua chong duong ((van toan) OR (van tan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((anh tang) or (nhan dang)) cua chong duong ((van toan) OR (van tan)) cau*".
