• Performing a fuzzy search may retrieve terms with similar spellings: (( danh tac va hoc vien nam ) or ((( dong bac van ((hoc mien) or (hoc hien)) nam ) or ((( danh cac van ho tien nam ) or ( danh ((cao van) OR (dao van)) ha hien nay ))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( danh tac va hoc vien nam ) OR ((( dong bac van ((hoc mien) OR (hoc hien)) nam ) OR ((( danh cac van ho tien nam ) OR ( danh ((cao van) OR (dao van)) ha hien nay )))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( danh tac va hoc vien nam ) or ((( dong bac van ((hoc mien) or (hoc hien)) nam ) or ((( danh cac van ho tien nam ) or ( danh ((cao van) OR (dao van)) ha hien nay ))))))".
• Adding a wildcard symbol may retrieve word variants: (( danh tac va hoc vien nam ) or ((( dong bac van ((hoc mien) or (hoc hien)) nam ) or ((( danh cac van ho tien nam ) or ( danh ((cao van) OR (dao van)) ha hien nay ))))))*.
