• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong hoang) OR (((how hong) OR (hong jong)))) wang yu chen tain du ((yang hui) OR (yang muxi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong hoang) or (((how hong) or (hong jong)))) wang yu chen tain du ((yang hui) OR (yang muxi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong hoang) or (((how hong) or (hong jong)))) wang yu chen tain du ((yang hui) OR (yang muxi)) ;*.
