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