• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (theo chieu)) tinh - thanh trung cua thuong thong dan ((thanh bac) OR (nhanh bac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (theo chieu)) tinh - thanh trung cua thuong thong dan ((thanh bac) OR (nhanh bac))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (theo chieu)) tinh - thanh trung cua thuong thong dan ((thanh bac) OR (nhanh bac))*.
