• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang wang hui wei ((((chang min) OR (chang ann))) OR (chang mae)) kong (sar OR saur) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang wang hui wei ((((chang min) OR (chang ann))) or (chang mae)) kong (sar or saur) ;*".
