• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky tang ma hoi. hieu ve cham so ((ban hanh) OR (((bang hinh) OR (hang chinh)))) vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky tang ma hoi. hieu ve cham so ((ban hanh) or (((bang hinh) OR (hang chinh)))) vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky tang ma hoi. hieu ve cham so ((ban hanh) or (((bang hinh) OR (hang chinh)))) vi cua tre*.
