• Performing a fuzzy search may retrieve terms with similar spellings: (( cong tac xa hoc viet nam ) or ((( ((danh bac) OR (dan bac)) dai hoc viet nam ) or ((( doanh bat dan hoc viet nam ) or ( dinh lam dan hoc viet nam ))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( cong tac xa hoc viet nam ) OR ((( ((danh bac) OR (dan bac)) dai hoc viet nam ) OR ((( doanh bat dan hoc viet nam ) OR ( dinh lam dan hoc viet nam )))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( cong tac xa hoc viet nam ) or ((( ((danh bac) OR (dan bac)) dai hoc viet nam ) or ((( doanh bat dan hoc viet nam ) or ( dinh lam dan hoc viet nam ))))))".
• Adding a wildcard symbol may retrieve word variants: (( cong tac xa hoc viet nam ) or ((( ((danh bac) OR (dan bac)) dai hoc viet nam ) or ((( doanh bat dan hoc viet nam ) or ( dinh lam dan hoc viet nam ))))))*.
