• Performing a fuzzy search may retrieve terms with similar spellings: (((( danh cac vung hoc ((phien nam) OR (hien nay)) ) or ( danh tac ((vung moc) or (dung mo)) nghien nam ))) or ((( danh cac van hoc vien nam ) or ( dinh chuc van hoc vien nam ))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((( danh cac vung hoc ((phien nam) OR (hien nay)) ) OR ( danh tac ((vung moc) OR (dung mo)) nghien nam ))) OR ((( danh cac van hoc vien nam ) OR ( dinh chuc van hoc vien nam )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( danh cac vung hoc ((phien nam) OR (hien nay)) ) or ( danh tac ((vung moc) or (dung mo)) nghien nam ))) or ((( danh cac van hoc vien nam ) or ( dinh chuc van hoc vien nam ))))".
• Adding a wildcard symbol may retrieve word variants: (((( danh cac vung hoc ((phien nam) OR (hien nay)) ) or ( danh tac ((vung moc) or (dung mo)) nghien nam ))) or ((( danh cac van hoc vien nam ) or ( dinh chuc van hoc vien nam ))))*.
