• If you are trying to use Boolean operators, they must be ALL CAPS: ((((lang fang) OR (jing fang))) OR (yang fan)) huang jing chih zheng ong chong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((lang fang) OR (jing fang))) or (yang fan)) huang jing chih zheng ong chong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((((lang fang) OR (jing fang))) or (yang fan)) huang jing chih zheng ong chong shu ;*.
