• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan chen) OR (kang chen)) ((via gan) OR (run pain)) yang jin ((chang has) OR (chang ha)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan chen) or (kang chen)) ((via gan) or (run pain)) yang jin ((chang has) OR (chang ha)) ;".
• Adding a wildcard symbol may retrieve word variants: wan ((yan chen) or (kang chen)) ((via gan) or (run pain)) yang jin ((chang has) OR (chang ha)) ;*.
