• If you are trying to use Boolean operators, they must be ALL CAPS: ((long tan) OR (long han)) tan chia jin ((ying jiao) OR (ping jia)) ((tong hui) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((long tan) OR (long han)) tan chia jin ((ying jiao) or (ping jia)) ((tong hui) or (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((long tan) OR (long han)) tan chia jin ((ying jiao) or (ping jia)) ((tong hui) or (gong hui)) ;*.
