• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (toc sach)) tu ((hang xa) OR (hoang xa)) hoi. hieu ve cam duc va hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (toc sach)) tu ((hang xa) OR (hoang xa)) hoi. hieu ve cam duc va hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (toc sach)) tu ((hang xa) OR (hoang xa)) hoi. hieu ve cam duc va hanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (toc sach)) tu ((hang xa) OR (hoang xa)) hoi. hieu ve cam duc va hanh vai cuu tre*.
