• If you are trying to use Boolean operators, they must be ALL CAPS: wei yang tang yi chen zheng min ((((jeong su) OR (rong su))) OR (jeong mi)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wei yang tang yi chen zheng min ((((jeong su) OR (rong su))) or (jeong mi)) ;*".
