• Performing a fuzzy search may retrieve terms with similar spellings: (( danh ban van hoc hien nam ) or ((((( danh ((dat van) OR (dam van)) hoc hien nam ) or ( dinh gia van hoc hien nam ))) or ((( danh bat van hoc hien nay ) or ( anh bai van hoc hien nay ))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( danh ban van hoc hien nam ) OR ((((( danh ((dat van) OR (dam van)) hoc hien nam ) OR ( dinh gia van hoc hien nam ))) OR ((( danh bat van hoc hien nay ) OR ( anh bai van hoc hien nay )))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( danh ban van hoc hien nam ) or ((((( danh ((dat van) OR (dam van)) hoc hien nam ) or ( dinh gia van hoc hien nam ))) or ((( danh bat van hoc hien nay ) or ( anh bai van hoc hien nay ))))))".
• Adding a wildcard symbol may retrieve word variants: (( danh ban van hoc hien nam ) or ((((( danh ((dat van) OR (dam van)) hoc hien nam ) or ( dinh gia van hoc hien nam ))) or ((( danh bat van hoc hien nay ) or ( anh bai van hoc hien nay ))))))*.
