• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (ho chieu)) xanh - hanh ((trung cua) OR (tang cua)) thong cong tuan thanh cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (ho chieu)) xanh - hanh ((trung cua) or (tang cua)) thong cong tuan thanh cac~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (ho chieu)) xanh - hanh ((trung cua) or (tang cua)) thong cong tuan thanh cac*.
