• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((jane chen) or (zhang hanmo)) ((run jin) OR (run gain)) kang chin chang sara ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((jane chen) or (zhang hanmo)) ((run jin) OR (run gain)) kang chin chang sara ;*.
