• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tu nang ((x hoi) OR (xa hoi)). hieu ve cham xuc ban danh de ((cua tre) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tu nang ((x hoi) OR (xa hoi)). hieu ve cham xuc ban danh de ((cua tre) or (cua tu))".
