• If you are trying to use Boolean operators, they must be ALL CAPS: ((cua chu) OR (theo chieu)) xanh - hanh trang cua thong cong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((cua chu) or (theo chieu)) xanh - hanh trang cua thong cong dan ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ((cua chu) or (theo chieu)) xanh - hanh trang cua thong cong dan ((toan cau) OR (toan cao))*.
