• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky tang van hoi. lieu ((va thai) OR (va tham)) do va hanh vi ((cuu tre) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky tang van hoi. lieu ((va thai) OR (va tham)) do va hanh vi ((cuu tre) OR (cua tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky tang van hoi. lieu ((va thai) OR (va tham)) do va hanh vi ((cuu tre) or (cua tre))".
• Adding a wildcard symbol may retrieve word variants: te sai ky tang van hoi. lieu ((va thai) OR (va tham)) do va hanh vi ((cuu tre) or (cua tre))*.
