• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) y lang ha hoi. hieu ve ((cam cuc) OR (cham cuu)) ban tinh dinh cu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) y lang ha hoi. hieu ve ((cam cuc) or (cham cuu)) ban tinh dinh cu tre".
