• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (te sach)) ky nang ma hoi. hieu ve cham luc va tinh vai ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (te sach)) ky nang ma hoi. hieu ve cham luc va tinh vai ((cua triet) OR (su triet))*".
