• If you are trying to use Boolean operators, they must be ALL CAPS: gang yao ((ying hua) OR (ming hua)) shen chang boon ((chong seo) OR (hong seo)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "gang yao ((ying hua) OR (ming hua)) shen chang boon ((chong seo) or (hong seo)) ;~".
• Adding a wildcard symbol may retrieve word variants: gang yao ((ying hua) OR (ming hua)) shen chang boon ((chong seo) or (hong seo)) ;*.
