• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((((wang lin) OR (wang qin))) OR (wang li)) li gang minh ((congo shu) OR (gong hui)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((wang lin) OR (wang qin))) or (wang li)) li gang minh ((congo shu) or (gong hui)) ;*".
