• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yuhan) OR (wang yidan)) ting jia shen zhang ((jian hong) OR (tin hong)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yuhan) OR (wang yidan)) ting jia shen zhang ((jian hong) or (tin hong)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yuhan) OR (wang yidan)) ting jia shen zhang ((jian hong) or (tin hong)) hai ;*.
