• Performing a fuzzy search may retrieve terms with similar spellings: (( danh tac can ((hoc vien) or (hoc viet)) nam ) or ((((( doanh tai dung mot tan nam ) or ( doanh tai ((cong moc) OR (cong uoc)) tien nam ))) or ((( danh tac nang hoc hien nam ) or ( danh tac ((trung hoc) or (trung quoc)) hien nam ))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( danh tac can ((hoc vien) OR (hoc viet)) nam ) OR ((((( doanh tai dung mot tan nam ) OR ( doanh tai ((cong moc) OR (cong uoc)) tien nam ))) OR ((( danh tac nang hoc hien nam ) OR ( danh tac ((trung hoc) OR (trung quoc)) hien nam ))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( danh tac can ((hoc vien) or (hoc viet)) nam ) or ((((( doanh tai dung mot tan nam ) or ( doanh tai ((cong moc) OR (cong uoc)) tien nam ))) or ((( danh tac nang hoc hien nam ) or ( danh tac ((trung hoc) or (trung quoc)) hien nam ))))))*".
