• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky sang ((lap hai) OR (lap hoat)). ((hieu ve) or (hieu va)) cam duc va thanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky sang ((lap hai) OR (lap hoat)). ((hieu ve) OR (hieu va)) cam duc va thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky sang ((lap hai) OR (lap hoat)). ((hieu ve) or (hieu va)) cam duc va thanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu san ky sang ((lap hai) OR (lap hoat)). ((hieu ve) or (hieu va)) cam duc va thanh vi cua te*.
