• If you are trying to use Boolean operators, they must be ALL CAPS: nan yan chang ann ((((gain yang) OR (yin yang))) OR (dan yang)) jin kyung (sar OR sara) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan yan chang ann ((((gain yang) OR (yin yang))) or (dan yang)) jin kyung (sar or sara) ;*".
