• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tay lang xa hoi. hieu ((va cam) OR (va cac)) xuc ((va thanh) OR (va tinh)) ha cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tay lang xa hoi. hieu ((va cam) OR (va cac)) xuc ((va thanh) or (va tinh)) ha cua viet".
