• Performing a fuzzy search may retrieve terms with similar spellings: phu sang ky nang ((van hoi) OR (van hoc)). lieu va cham xuc van hanh di ((cua triet) or (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: phu sang ky nang ((van hoi) OR (van hoc)). lieu va cham xuc van hanh di ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "phu sang ky nang ((van hoi) OR (van hoc)). lieu va cham xuc van hanh di ((cua triet) or (va triet))".
• Adding a wildcard symbol may retrieve word variants: phu sang ky nang ((van hoi) OR (van hoc)). lieu va cham xuc van hanh di ((cua triet) or (va triet))*.
