• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yang liang) OR (yan yuan))) OR (quan guo)) yi chen ((han min) OR (han men)) jeong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang liang) or (yan yuan))) or (quan guo)) yi chen ((han min) OR (han men)) jeong shu ;*".
