• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ky ((nang ma) OR (nang cao)) hoi. ((hieu ve) or (hieu va)) cam luc va thanh vai cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky ((nang ma) OR (nang cao)) hoi. ((hieu ve) OR (hieu va)) cam luc va thanh vai cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky ((nang ma) OR (nang cao)) hoi. ((hieu ve) or (hieu va)) cam luc va thanh vai cua vat".
• Adding a wildcard symbol may retrieve word variants: tu sai ky ((nang ma) OR (nang cao)) hoi. ((hieu ve) or (hieu va)) cam luc va thanh vai cua vat*.
