• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong bin) OR (dong hoang))) OR (dong sin)) yale yu chen tan amin ((hong ghi) OR (hong hai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong bin) or (dong hoang))) or (dong sin)) yale yu chen tan amin ((hong ghi) OR (hong hai)) ;*".
