• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) ky ((danh xa) OR (canh xa)) hoi. lieu va cac tuc va dan vat su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky ((danh xa) OR (canh xa)) hoi. lieu va cac tuc va dan vat su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky ((danh xa) OR (canh xa)) hoi. lieu va cac tuc va dan vat su triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ky ((danh xa) OR (canh xa)) hoi. lieu va cac tuc va dan vat su triet*.
