• If you are trying to use Boolean operators, they must be ALL CAPS: qian ((wang yang) OR (gong liutang)) di ((chen hong) OR (chen yong)) hong rong su ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian ((wang yang) or (gong liutang)) di ((chen hong) OR (chen yong)) hong rong su ;*".
