• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty xang ((ma hoi) OR (xa hoi)). hieu va ((tham duc) OR (tham du)) va hanh lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty xang ((ma hoi) OR (xa hoi)). hieu va ((tham duc) or (tham du)) va hanh lai cua triet".
