• Performing a fuzzy search may retrieve terms with similar spellings: ((su cac) or (tu cac)) ky nang ho hoi. hieu ve ((cham tuc) OR (nham thuc)) van hanh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su cac) OR (tu cac)) ky nang ho hoi. hieu ve ((cham tuc) OR (nham thuc)) van hanh di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su cac) or (tu cac)) ky nang ho hoi. hieu ve ((cham tuc) OR (nham thuc)) van hanh di cua triet*".
