• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan wang heat gain ((((yang lin) OR (wang lin))) OR (yang li)) ((hong a) OR (hong hong)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan wang heat gain ((((yang lin) OR (wang lin))) or (yang li)) ((hong a) or (hong hong)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan wang heat gain ((((yang lin) OR (wang lin))) or (yang li)) ((hong a) or (hong hong)) ;*.
