• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yuan) OR (wang yuhan)) wang jia shen ((chan kang) OR (zhang ming)) ((hong g) OR (hong 7)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yuan) or (wang yuhan)) wang jia shen ((chan kang) or (zhang ming)) ((hong g) OR (hong 7)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yuan) or (wang yuhan)) wang jia shen ((chan kang) or (zhang ming)) ((hong g) OR (hong 7)) ;*.
