• If you are trying to use Boolean operators, they must be ALL CAPS: tu cam ((ky lang) OR (ky dang)) van hoi. hieu ve pham cuc ban thanh san ((cau treo) OR (cau triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cam ((ky lang) OR (ky dang)) van hoi. hieu ve pham cuc ban thanh san ((cau treo) or (cau triet))".
• Adding a wildcard symbol may retrieve word variants: tu cam ((ky lang) OR (ky dang)) van hoi. hieu ve pham cuc ban thanh san ((cau treo) or (cau triet))*.
