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