• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (theo chieu)) sang - manh trung cap thong cong van ((tuan tap) OR (tuan tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (theo chieu)) sang - manh trung cap thong cong van ((tuan tap) OR (tuan tai))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (theo chieu)) sang - manh trung cap thong cong van ((tuan tap) OR (tuan tai))*.
