• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((nang xa) or (nang ma)) hoi. nhieu viec va thuc ((cao dan) OR (cao danh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (nang ma)) hoi. nhieu viec va thuc ((cao dan) OR (cao danh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) or (nang ma)) hoi. nhieu viec va thuc ((cao dan) OR (cao danh)) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((nang xa) or (nang ma)) hoi. nhieu viec va thuc ((cao dan) OR (cao danh)) vi cua tre*.
