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