• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ((thu nang) OR (thi nang)) xa hoi. hieu ve cam tuc van hang di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) ((thu nang) or (thi nang)) xa hoi. hieu ve cam tuc van hang di cua triet*".
