• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) tinh - thanh dong xuan thong ((cong tac) OR (cong ty)) than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) tinh - thanh dong xuan thong ((cong tac) or (cong ty)) than cau".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) tinh - thanh dong xuan thong ((cong tac) or (cong ty)) than cau*.
