• If you are trying to use Boolean operators, they must be ALL CAPS: ((liang dan) OR (((dong di) OR (dong sin)))) ((yang yao) OR (yang yang)) feng han jie song ming ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((liang dan) or (((dong di) or (dong sin)))) ((yang yao) OR (yang yang)) feng han jie song ming ;~".
• Adding a wildcard symbol may retrieve word variants: ((liang dan) or (((dong di) or (dong sin)))) ((yang yao) OR (yang yang)) feng han jie song ming ;*.
