• If you are trying to use Boolean operators, they must be ALL CAPS: wing tan ((yan yi) OR (tan li)) chen zheng hong ((jong shu) OR (tong shui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing tan ((yan yi) or (tan li)) chen zheng hong ((jong shu) OR (tong shui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing tan ((yan yi) or (tan li)) chen zheng hong ((jong shu) OR (tong shui)) ;*.
