• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y dang ma hoa. ((hieu van) OR (thien van)) ((nam xuc) OR (cam xuc)) va danh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y dang ma hoa. ((hieu van) or (thien van)) ((nam xuc) OR (cam xuc)) va danh vai cua triet".
