• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky lang ((ha hoi) OR (ha noi)). hieu qua cham xuc ((gia thanh) or (va hanh)) lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang ((ha hoi) OR (ha noi)). hieu qua cham xuc ((gia thanh) OR (va hanh)) lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang ((ha hoi) OR (ha noi)). hieu qua cham xuc ((gia thanh) or (va hanh)) lai cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang ((ha hoi) OR (ha noi)). hieu qua cham xuc ((gia thanh) or (va hanh)) lai cua triet*.
