• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sai) OR (tu bai)) ky lang van hoa. hieu ve cac nuoc ((va hanh) or (van anh)) vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sai) OR (tu bai)) ky lang van hoa. hieu ve cac nuoc ((va hanh) OR (van anh)) vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sai) OR (tu bai)) ky lang van hoa. hieu ve cac nuoc ((va hanh) or (van anh)) vai cua tre*".
