• If you are trying to use Boolean operators, they must be ALL CAPS: tu cai ky nang ma hoi. hieu ve ((cac luc) OR (cau luc)) va danh ((ca cua) OR (con cua)) cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cai ky nang ma hoi. hieu ve ((cac luc) OR (cau luc)) va danh ((ca cua) or (con cua)) cu".
• Adding a wildcard symbol may retrieve word variants: tu cai ky nang ma hoi. hieu ve ((cac luc) OR (cau luc)) va danh ((ca cua) or (con cua)) cu*.
