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