• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thi hanh xa hoi. hieu ve ((cam luc) OR (cau luc)) va ((thanh lam) OR (thanh lap)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thi hanh xa hoi. hieu ve ((cam luc) OR (cau luc)) va ((thanh lam) or (thanh lap)) va triet".
• Adding a wildcard symbol may retrieve word variants: te sach thi hanh xa hoi. hieu ve ((cam luc) OR (cau luc)) va ((thanh lam) or (thanh lap)) va triet*.
