• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang ma hoi. lieu va cac xuc va ((tinh ca) OR (tinh cao)) ((cuu tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang ma hoi. lieu va cac xuc va ((tinh ca) OR (tinh cao)) ((cuu tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang ma hoi. lieu va cac xuc va ((tinh ca) OR (tinh cao)) ((cuu tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang ma hoi. lieu va cac xuc va ((tinh ca) OR (tinh cao)) ((cuu tre) or (cua triet))*.
