• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thu sach)) ky nang xa hoi. hieu ve ((cam tuc) OR (nam thuc)) van hanh thai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ky nang xa hoi. hieu ve ((cam tuc) OR (nam thuc)) van hanh thai cuu tre.
