_loadItems(_page) async {
    List _elements =[];

    final _transport = ConsoleHttpTransport(Uri.parse('http://test.ru:9200/'));
    final _client = elastic.Client(_transport);

    final _result = await _client.search(
      'kpmi_etalon_obj', '',
      // elastic.Query.matchAll(),
      // source: true,
      elastic.Query.term('project.code', ['001', '002', '003', '004', '005', '006', '007', '008', '009']),
      source: ['shortName','project.name','stateWork'],
      offset: _page*20,
      limit: 20
    );
    final _resultFin = _result.toMap();
    countElements = _resultFin['totalCount'];
    _elements = _resultFin['hits'];
    _elements.forEach((element) {
    final record = ElementList(
        id: element['_id'],
        title: element['doc']['project']['name'],
        subtitle: element['doc']['shortName'],
        leading: element['doc']['stateWork'],
        // trailing: element['doc']['cost'].toString()
        );
        items.add(record); 
    });
    setState(() {});
    _transport.close();
  }
