• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky lang) OR (ky dang)) xa hoi. lieu va ((hau luc) OR (nhan luc)) ban hanh dieu cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky lang) OR (ky dang)) xa hoi. lieu va ((hau luc) or (nhan luc)) ban hanh dieu cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky lang) OR (ky dang)) xa hoi. lieu va ((hau luc) or (nhan luc)) ban hanh dieu cua triet*.
