• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (doc hieu)) xanh - ((can ban) OR (van ban)) cua thong thong thanh phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (doc hieu)) xanh - ((can ban) or (van ban)) cua thong thong thanh phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (doc hieu)) xanh - ((can ban) or (van ban)) cua thong thong thanh phan cau*.
