• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) ((lang hoa) OR (hang hoa)) hoi. hieu ve cam thuc va danh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach y)) ((lang hoa) or (hang hoa)) hoi. hieu ve cam thuc va danh vi cua triet*".
