• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) xanh - manh truong cua tong huong dan ((toan tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) xanh - manh truong cua tong huong dan ((toan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) xanh - manh truong cua tong huong dan ((toan tai) or (toan ban))*.
