• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ky dang xa hoi. hieu ve ((cam xuc) OR (pham cuc)) ban hanh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ky dang xa hoi. hieu ve ((cam xuc) or (pham cuc)) ban hanh va cua tre*".
