• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((hyoung tan) OR (hong tan)) ((hua chen) OR (yu chen)) yang du wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((hyoung tan) OR (hong tan)) ((hua chen) or (yu chen)) yang du wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((hyoung tan) OR (hong tan)) ((hua chen) or (yu chen)) yang du wong siu ;*.
