• If you are trying to use Boolean operators, they must be ALL CAPS: main ((((hong wang) OR (hong gang))) OR (hong kong)) hua rene yan jiu ((hong shu) OR (hong ghi)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "main ((((hong wang) OR (hong gang))) or (hong kong)) hua rene yan jiu ((hong shu) or (hong ghi)) ;*".
