• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang xa hoi. lieu ((va cam) OR (va cao)) tuc ((va hanh) or (va dan)) thai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. lieu ((va cam) OR (va cao)) tuc ((va hanh) OR (va dan)) thai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. lieu ((va cam) OR (va cao)) tuc ((va hanh) or (va dan)) thai cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. lieu ((va cam) OR (va cao)) tuc ((va hanh) or (va dan)) thai cua triet*.
