• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky nang ma hoi. hieu ((ve cam) OR (ve cac)) xuc ban thanh tai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ky nang ma hoi. hieu ((ve cam) OR (ve cac)) xuc ban thanh tai cua triet".
