• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((yuan lin) OR (wang qin)) yi ((((rong ming) OR (song min))) OR (song ming)) congo shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yuan lin) or (wang qin)) yi ((((rong ming) OR (song min))) or (song ming)) congo shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yuan lin) or (wang qin)) yi ((((rong ming) OR (song min))) or (song ming)) congo shu ;*.
