• If you are trying to use Boolean operators, they must be ALL CAPS: ((long tas) OR (long days)) tuan china dan ((((yang jie) OR (yang di))) OR (ying jin)) gong hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((long tas) or (long days)) tuan china dan ((((yang jie) OR (yang di))) or (ying jin)) gong hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((long tas) or (long days)) tuan china dan ((((yang jie) OR (yang di))) or (ying jin)) gong hui ;*.
