• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky ((((nang xa) OR (mang xa))) or (nang ma)) hoi. lieu van tham luoc van hanh lai cau trieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky ((((nang xa) OR (mang xa))) OR (nang ma)) hoi. lieu van tham luoc van hanh lai cau trieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky ((((nang xa) OR (mang xa))) or (nang ma)) hoi. lieu van tham luoc van hanh lai cau trieu".
• Adding a wildcard symbol may retrieve word variants: vu sach ky ((((nang xa) OR (mang xa))) or (nang ma)) hoi. lieu van tham luoc van hanh lai cau trieu*.
