• If you are trying to use Boolean operators, they must be ALL CAPS: wing tan ((cong run) OR (cong sun)) ((((yan wang) OR (yang yang))) OR (yuan wang)) yan hong ma ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing tan ((cong run) or (cong sun)) ((((yan wang) OR (yang yang))) or (yuan wang)) yan hong ma ;~".
• Adding a wildcard symbol may retrieve word variants: wing tan ((cong run) or (cong sun)) ((((yan wang) OR (yang yang))) or (yuan wang)) yan hong ma ;*.
