• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((lo lang) OR (o lang)) xa hoi. hieu ve ((cham xuc) OR (chat xuc)) gia thanh toan cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((lo lang) OR (o lang)) xa hoi. hieu ve ((cham xuc) or (chat xuc)) gia thanh toan cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ((lo lang) OR (o lang)) xa hoi. hieu ve ((cham xuc) or (chat xuc)) gia thanh toan cua triet*.
