• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong wang hui ((((skin chang) OR (jin chang))) OR (shiyan chang)) jin (cong OR kong) shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong wang hui ((((skin chang) OR (jin chang))) or (shiyan chang)) jin (cong or kong) shu ;*".
