• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty sang ma hoi. hieu va ((((cam tuc) OR (nam thuc))) OR (cam xuc)) va hang thai va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty sang ma hoi. hieu va ((((cam tuc) OR (nam thuc))) or (cam xuc)) va hang thai va triet*".
