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