• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan yang jin ((((shiyan chang) OR (chin chang))) OR (han chang)) min jeong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan yang jin ((((shiyan chang) OR (chin chang))) or (han chang)) min jeong shu ;*".
