• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((y lang) or (hoi lang)) van hoi. ((chieu tu) OR (chu tu)) cham xuc ban vanh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y lang) OR (hoi lang)) van hoi. ((chieu tu) OR (chu tu)) cham xuc ban vanh dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y lang) or (hoi lang)) van hoi. ((chieu tu) OR (chu tu)) cham xuc ban vanh dai cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ((y lang) or (hoi lang)) van hoi. ((chieu tu) OR (chu tu)) cham xuc ban vanh dai cua tre*.
