• Performing a fuzzy search may retrieve terms with similar spellings: ((dong yang) or (dong sin)) ya hua rene yan tin ((((hong g) OR (hong ng))) or (dang hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong yang) OR (dong sin)) ya hua rene yan tin ((((hong g) OR (hong ng))) OR (dang hai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) or (dong sin)) ya hua rene yan tin ((((hong g) OR (hong ng))) or (dang hai)) ;*".
