• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky tang ((van hoi) OR (van hoc)). hieu van nam luc va thanh vi ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky tang ((van hoi) or (van hoc)). hieu van nam luc va thanh vi ((cua triet) OR (cua viet))*".
