• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ky tang ((lai roi) or (((dai hoa) OR (dai khoa)))). hieu su cam xuc va hanh dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky tang ((lai roi) OR (((dai hoa) OR (dai khoa)))). hieu su cam xuc va hanh dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky tang ((lai roi) or (((dai hoa) OR (dai khoa)))). hieu su cam xuc va hanh dai cua te".
• Adding a wildcard symbol may retrieve word variants: tu sai ky tang ((lai roi) or (((dai hoa) OR (dai khoa)))). hieu su cam xuc va hanh dai cua te*.
