• Performing a fuzzy search may retrieve terms with similar spellings: ((su cac) or (tu cac)) ky ((trang xa) OR (trong xa)) hoi. hieu va dang duc gia thanh hoa van trien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su cac) OR (tu cac)) ky ((trang xa) OR (trong xa)) hoi. hieu va dang duc gia thanh hoa van trien*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su cac) or (tu cac)) ky ((trang xa) OR (trong xa)) hoi. hieu va dang duc gia thanh hoa van trien*".
