• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((((yan han) OR (yan zhang))) OR (kang han)) ((run dan) OR (run pain)) yang jin hong w ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((((yan han) OR (yan zhang))) or (kang han)) ((run dan) or (run pain)) yang jin hong w ;*".
