• If you are trying to use Boolean operators, they must be ALL CAPS: wan yuan kang hua en ((ying jin) OR (yang jin)) ((((kong eiu) OR (tonga eiu))) OR (kong your)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yuan kang hua en ((ying jin) or (yang jin)) ((((kong eiu) OR (tonga eiu))) or (kong your)) ;*".
