• Performing a fuzzy search may retrieve terms with similar spellings: su ((((((sach nganh) OR (cach nhanh))) or (sach tranh))) or (sach ngan)) co khi đong luc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((((((sach nganh) OR (cach nhanh))) OR (sach tranh))) OR (sach ngan)) co khi đong luc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((((((sach nganh) OR (cach nhanh))) or (sach tranh))) or (sach ngan)) co khi đong luc".
• Adding a wildcard symbol may retrieve word variants: su ((((((sach nganh) OR (cach nhanh))) or (sach tranh))) or (sach ngan)) co khi đong luc*.
