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