• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky hang hoa noi. hieu ((va cham) OR (((vu cham) OR (tu cham)))) hoc va dan vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky hang hoa noi. hieu ((va cham) or (((vu cham) OR (tu cham)))) hoc va dan vi cuu tre".
