• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((y hang) OR (ly hang)) ((ma hoi) OR (ma hoa)). hieu ve cham loc va hanh va cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((y hang) OR (ly hang)) ((ma hoi) or (ma hoa)). hieu ve cham loc va hanh va cua triet".
