扫描python助手在Elasticsearch中带有切片

Question

我有以下代码：

client = Elasticsearch(hosts=['host'], port=9200)
scan_arguments = {'query': {'slice': {'max': 1, 'id': 0}}, 'preference': '_shards:0', 'index': u'my_index'}
for hit in scan(client, **scan_args):
    # do something with hit

我会收到以下错误

RequestError: TransportError(400, u'parsing_exception', u'[slice] failed to parse field [max]')

如何在扫描函数中传递切片参数？

Answer 1

" max"在我的经验中必须是> 1。使用" max"之前，我看到了相同的错误：1。

Answer 2

HTTP API的原始错误表示max必须大于1。

{
  "error": {
    "root_cause": [
      {
        "type": "x_content_parse_exception",
        "reason": "[3:20] [slice] failed to parse field [max]"
      }
    ],
    "type": "x_content_parse_exception",
    "reason": "[3:20] [slice] failed to parse field [max]",
    "caused_by": {
      "type": "illegal_argument_exception",
      "reason": "max must be greater than 1"
    }
  },
  "status": 400
}
