• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong can) OR (dong cao)) say chuan daun sang minh ((hong g) OR (zhong tai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong can) OR (dong cao)) say chuan daun sang minh ((hong g) or (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong can) OR (dong cao)) say chuan daun sang minh ((hong g) or (zhong tai)) ;*.
