• 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) OR (nam thuc)) va thanh vi cua triet*.
• 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) OR (nam thuc)) va thanh vi cua triet*".
