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