• If you are trying to use Boolean operators, they must be ALL CAPS: ((thien chien) OR (ho chieu)) xanh - thanh dung ((van dung) OR (van dong)) cong tan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thien chien) or (ho chieu)) xanh - thanh dung ((van dung) OR (van dong)) cong tan toan cau".
• Adding a wildcard symbol may retrieve word variants: ((thien chien) or (ho chieu)) xanh - thanh dung ((van dung) OR (van dong)) cong tan toan cau*.
