• If you are trying to use Boolean operators, they must be ALL CAPS: lang yang liang wei gene ((tan tan) OR (tang tang)) ((zhong tai) OR (hong hong)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yang liang wei gene ((tan tan) OR (tang tang)) ((zhong tai) or (hong hong)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yang liang wei gene ((tan tan) OR (tang tang)) ((zhong tai) or (hong hong)) ;*.
