• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky tang mai hoi. hieu ve cam ((xuc va) OR (truc va)) hanh lai chau tho*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ky tang mai hoi. hieu ve cam ((xuc va) or (truc va)) hanh lai chau tho*".
