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