• If you are trying to use Boolean operators, they must be ALL CAPS: wang liang ((yang lin) OR (yang xi)) test a min ((jeong yeon) OR (jeong hyeok)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ((yang lin) or (yang xi)) test a min ((jeong yeon) OR (jeong hyeok)) ;*".
