• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yan liang) OR (you liang))) OR (yang guang)) ((yuan fei) OR (yuan hui)) pei yun 3 long du ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yan liang) OR (you liang))) or (yang guang)) ((yuan fei) or (yuan hui)) pei yun 3 long du ;*".
