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