• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cach) or (vu sach)) ky tang ((ma noi) OR (ha noi)). hieu ve cam thuc vat hang de cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (vu sach)) ky tang ((ma noi) OR (ha noi)). hieu ve cam thuc vat hang de cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (vu sach)) ky tang ((ma noi) OR (ha noi)). hieu ve cam thuc vat hang de cuu tre*".
