• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan change) OR (mean change)) a gene yang ((min hong) OR (tin hong)) hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan change) OR (mean change)) a gene yang ((min hong) or (tin hong)) hai ;*".
