• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky nang xa hoi. hieu thien hach nuoc va danh ((vi cua) OR (((vai cua) OR (lai cua)))) tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky nang xa hoi. hieu thien hach nuoc va danh ((vi cua) or (((vai cua) OR (lai cua)))) tu~".
• Adding a wildcard symbol may retrieve word variants: so sach ky nang xa hoi. hieu thien hach nuoc va danh ((vi cua) or (((vai cua) OR (lai cua)))) tu*.
