• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang xay hoi. hieu ve ((cao duc) OR (cao suc)) va tinh ((lam cua) OR (lai cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang xay hoi. hieu ve ((cao duc) OR (cao suc)) va tinh ((lam cua) or (lai cua)) triet*".
