• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky vang tao hoi. ((hieu ve) OR (((hieu va) OR (hieu qua)))) cac duc ban lanh hai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky vang tao hoi. ((hieu ve) or (((hieu va) OR (hieu qua)))) cac duc ban lanh hai cua triet~".
• Adding a wildcard symbol may retrieve word variants: su sach ky vang tao hoi. ((hieu ve) or (((hieu va) OR (hieu qua)))) cac duc ban lanh hai cua triet*.
