• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chau) OR (theo chieu)) tinh - thanh trung ve nhung cong tan ((hoa tap) OR (hoa tin))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chau) OR (theo chieu)) tinh - thanh trung ve nhung cong tan ((hoa tap) or (hoa tin))~".
• Adding a wildcard symbol may retrieve word variants: ((theo chau) OR (theo chieu)) tinh - thanh trung ve nhung cong tan ((hoa tap) or (hoa tin))*.
