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