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