• Performing a fuzzy search may retrieve terms with similar spellings: ((nuoc sach) OR (hoc sach)) van nang xa hoi. ((hieu ke) or (hieu ky)) cau chuc van hang di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((nuoc sach) OR (hoc sach)) van nang xa hoi. ((hieu ke) OR (hieu ky)) cau chuc van hang di cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nuoc sach) OR (hoc sach)) van nang xa hoi. ((hieu ke) or (hieu ky)) cau chuc van hang di cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((nuoc sach) OR (hoc sach)) van nang xa hoi. ((hieu ke) or (hieu ky)) cau chuc van hang di cuu tre*.
