• Performing a fuzzy search may retrieve terms with similar spellings: (( danh ((tac van) or (tac can)) hoc ((tieng nam) or (tieng nhat)) ) or ((( danh bac van hoc hien nam ) or ((( ((((danh cac) OR (hanh cac))) or (dinh cac)) van hieu mien nam ) or ( danh ca van dao mien nam ))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( danh ((tac van) OR (tac can)) hoc ((tieng nam) OR (tieng nhat)) ) OR ((( danh bac van hoc hien nam ) OR ((( ((((danh cac) OR (hanh cac))) OR (dinh cac)) van hieu mien nam ) OR ( danh ca van dao mien nam )))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( danh ((tac van) or (tac can)) hoc ((tieng nam) or (tieng nhat)) ) or ((( danh bac van hoc hien nam ) or ((( ((((danh cac) OR (hanh cac))) or (dinh cac)) van hieu mien nam ) or ( danh ca van dao mien nam ))))))".
