• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yong gang) OR (hong gang)) ((yan tan) OR (tan tan)) huang jin chang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong gang) OR (hong gang)) ((yan tan) or (tan tan)) huang jin chang hay ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong gang) OR (hong gang)) ((yan tan) or (tan tan)) huang jin chang hay ;*.
