elasticsearch - Elasticsearch 缩放 float 不接受数据

Question

以下是索引 index_new 的映射

{
    "mappings": {
        "_doc": {
            "properties": {
                "title": {
                    "type": "text"
                },
                "name": {
                    "type": "text"
                },
                "age": {
                    "type": "integer"
                },
                "price_amount": {
                    "properties": {
                        "val": {
                            "type": "scaled_float",
                            "scaling_factor": 100
                        }
                    }
                }
            }
        }
    }
}

将数据添加到索引中

curl -X POST \
  http://localhost:9200/new_index1/1 \
  -H 'Content-Type: application/json' \
  -d '{
     "title":    "new data for index",
        "name":     "balakarthik",
        "age":      24,
        "price_amount": {
            "val": 1005,
            "scaling_factor": 100   
        }

}'

这会返回一个错误

{
    "error": {
        "root_cause": [
            {
                "type": "mapper_parsing_exception",
                "reason": "failed to parse"
            }
        ],
        "type": "mapper_parsing_exception",
        "reason": "failed to parse",
        "caused_by": {
            "type": "illegal_argument_exception",
            "reason": "Field [val] misses required parameter [scaling_factor]"
        }
    },
    "status": 400
}

由于映射中已经提供了比例因子，我们是否需要在每个请求中发送比例因子，如果需要，那么我们需要如何在每个请求中发送比例因子。

我遇到了这个错误，但通过更改 URL 解决了这个问题。

您的 PUT 应该转到:http://localhost:9200/new_index1/_doc/1

此外，您应该将输入数据更改为仅指定值。像这样:

{
  "title": "new data for index",
  "name": "balakarthik",
  "age": 24,
  "price_amount": 10.05
}
