• If you are trying to use Boolean operators, they must be ALL CAPS: yang yan liang heat gain ((yang li) OR (yang yi)) ((((hong g) OR (hong 7))) OR (hong kong)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yan liang heat gain ((yang li) or (yang yi)) ((((hong g) OR (hong 7))) or (hong kong)) ;*".
