• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing yan) OR (dong di)) ((yan yuan) OR (fang yuan)) li yuan kang wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing yan) or (dong di)) ((yan yuan) OR (fang yuan)) li yuan kang wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing yan) or (dong di)) ((yan yuan) OR (fang yuan)) li yuan kang wong siu ;*.
