• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (bo sach)) ky lang xa hoi. hieu ve cam tuc va ((hang di) OR (hang dien)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (bo sach)) ky lang xa hoi. hieu ve cam tuc va ((hang di) OR (hang dien)) cua tre*".
