• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thieu hanh xa hoi. hieu ((ve cam) OR (vien cac)) tuc va hanh dam ((va triet) OR (va trien)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thieu hanh xa hoi. hieu ((ve cam) or (vien cac)) tuc va hanh dam ((va triet) OR (va trien))".
