• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) ky ((nang xa) OR (nang ma)) hoi. hieu ve chao xu va tinh via cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky ((nang xa) OR (nang ma)) hoi. hieu ve chao xu va tinh via cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky ((nang xa) OR (nang ma)) hoi. hieu ve chao xu va tinh via cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ky ((nang xa) OR (nang ma)) hoi. hieu ve chao xu va tinh via cuu tre*.
