• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling ((yang api) or (yang dali)) test law main ((jeong yeon) OR (jeong hyeok)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling ((yang api) or (yang dali)) test law main ((jeong yeon) OR (jeong hyeok)) ;*.
