• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y danh xa hoi. hieu ve cac duc van anh hai ((cua triet) OR (((cua viet) OR (ca viet)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y danh xa hoi. hieu ve cac duc van anh hai ((cua triet) or (((cua viet) OR (ca viet))))".
