• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (wang yanling))) OR (dong di)) a unit cost land rites among w ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yang) OR (wang yanling))) or (dong di)) a unit cost land rites among w ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) OR (wang yanling))) or (dong di)) a unit cost land rites among w ;*.
