• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky tang ma hoi. hieu ((ve cac) OR (va cac)) ((xuc va) OR (duc va)) hanh ca cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky tang ma hoi. hieu ((ve cac) or (va cac)) ((xuc va) OR (duc va)) hanh ca cua triet".
