• Performing a fuzzy search may retrieve terms with similar spellings: ((((dong di) or (dong hoang))) or (dong sin)) yale yu cheng jian amin ((hong ghi) OR (hong hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong di) OR (dong hoang))) OR (dong sin)) yale yu cheng jian amin ((hong ghi) OR (hong hai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong di) or (dong hoang))) or (dong sin)) yale yu cheng jian amin ((hong ghi) OR (hong hai)) ;*".
