• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((((yuan zi) OR (yan zi))) OR (yuan li)) zhen zhang kim song thin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((((yuan zi) OR (yan zi))) or (yuan li)) zhen zhang kim song thin ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((((yuan zi) OR (yan zi))) or (yuan li)) zhen zhang kim song thin ;*.
