                for (var index = 1; index < data.length; index++) {
                    var newPlaque: any = _.object(cols, data[index]);

                    if (!newPlaque.main_photo

                        continue;
                    }

                    newPlaque.search_key = getSearchKey(newPlaque);
                    newPlaque.erected_decade = newPlaque.erected.substring(0, 3) + '0';
                    plaqueList.push(newPlaque);
                };

                res(plaqueList);
