• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky nang van hoe. hieu va nam xuc ((van hanh) OR (van thanh)) vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ky nang van hoe. hieu va nam xuc ((van hanh) OR (van thanh)) vi cua triet*".
