• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((sang ma) or (((tang ma) OR (tang van)))) hoi. hieu ve cam tuc xa hanh dai va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((sang ma) OR (((tang ma) OR (tang van)))) hoi. hieu ve cam tuc xa hanh dai va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((sang ma) or (((tang ma) OR (tang van)))) hoi. hieu ve cam tuc xa hanh dai va triet".
• Adding a wildcard symbol may retrieve word variants: su sach ky ((sang ma) or (((tang ma) OR (tang van)))) hoi. hieu ve cam tuc xa hanh dai va triet*.
