• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) kho ((tang ma) or (tang van)) hoi. lieu va cac thuc van thanh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) kho ((tang ma) OR (tang van)) hoi. lieu va cac thuc van thanh di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) kho ((tang ma) or (tang van)) hoi. lieu va cac thuc van thanh di cua triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) kho ((tang ma) or (tang van)) hoi. lieu va cac thuc van thanh di cua triet*.
