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