• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (vu sach)) ky lang xa hoi. hieu vien ((cac bao) OR (cach bao)) va thanh van cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (vu sach)) ky lang xa hoi. hieu vien ((cac bao) OR (cach bao)) va thanh van cua triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (vu sach)) ky lang xa hoi. hieu vien ((cac bao) OR (cach bao)) va thanh van cua triet*.
