• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (tu cach))) OR (te sach)) y nang x hoi. thien van bao duc dang thanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sach) OR (tu cach))) or (te sach)) y nang x hoi. thien van bao duc dang thanh vai cuu tre*".
