Question

我正在使用python-elasticsearch客户端 - elasticsearch.py，当我尝试使用update_by_query方法更新文档时，弹性搜索无法解析查询。

我的更新机构如下：

{
  'script': {
    'inline': 'ctx._source.viewers += info',
    'params': {
      'info': {
        'time': datetime.datetime(2017, 3, 7, 18, 8, 50),
        'viewer': 'abc@xyz.com'
      }
    }
  }
}

弹性搜索的调用如下::

update = es.update_by_query(index=index_el,
                            doc_type='1',
                            q='delivery_reference_id:' + str(cam_id) +'',
                            body=doc)

cam_id的示例值为：

CAM_10_DATA_4_2017-03-07 18:02:07

在内部，形成以下查询::

http://127.0.0.1:9200/user_tracker/1/_update_by_query?q=delivery_reference_id%3ACAM_10_DATA_4_2017-03-07+18%3A02%3A07

收到的错误如下：

TransportError(400, 'search_phase_execution_exception', 'Failed to parse query [delivery_reference_id:CAM_10_DATA_4_2017-03-07 18:02:07]')

完整的错误日志如下：

如果有人想出来会很好。如果需要更多信息，请告诉我。

欣赏它。提前谢谢。

我认为您的查询语法不是最新的。我用以下语法得到了很好的结果：

{
  "query": {
    "bool": {
      "must": [
        { "match": { "MYFIELD": "myoldvalue" } }
      ]
    }
  },
  "script": {
    "inline": "ctx._source.MYFIELD = \"mynewvalue\"",
    "lang": "painless"
  }
}
