Question

我向Elasticsearch记录了一些数据。但是我的模板效果不好，并且位置数据是动态映射的。我想用查询脚本重新索引所有数据。如何将位置数据转换为几何形状？

样本数据：

plt.plot(something)
plt.show()

{ "deviceId": "dev1", "location": { "type": "Point", "coordinates": [ 28.891983032226562, 41.02446333535115 ] } }字段映射为type，而text映射为coordinates。

float索引放置映射请求：

test3

我的重新编制索引脚本（已编辑）：

PUT /test3
{
    "mappings": {
        "doc": {
            "properties": {
                "location": {
                    "type": "geo_shape",
                    "tree": "quadtree",
                    "precision": "100m"
                }
            }
        }
    }
}

Elasticsearch回复：

POST _reindex
{

  "size": 1000,
  "source": {

    "index": "test"
    , "query": {
      "constant_score": {
      "filter": {
        "exists": {
          "field": "location"
        }
      }
    }
    }
  },
  "dest": {
    "index": "test3"
  },
  "script":{
    "inline": "if(ctx._source.location.size()>1) {ctx._source.templocation=ctx._source.remove('location'); ctx._source['location.type'] = 'Point';  ctx._source['location.coordinates'] = ctx._source.templocation; ctx._source.remove('templocation'); } "
  }
}

{ "took": 172, "timed_out": false, "total": 2, "updated": 0, "created": 0, "deleted": 0, "batches": 1, "version_conflicts": 0, "noops": 0, "retries": { "bulk": 0, "search": 0 }, "throttled_millis": 0, "requests_per_second": -1, "throttled_until_millis": 0, "failures": [ { "index": "test3", "type": "data", "id": "AWXsdV-z29dKQeP_vT68", "cause": { "type": "illegal_argument_exception", "reason": "[location] is defined as an object in mapping [data] but this name is already used for a field in other types" }, "status": 400 }, { "index": "test3", "type": "data", "id": "AWXsdVAP29dKQeP_vT67", "cause": { "type": "illegal_argument_exception", "reason": "[location] is defined as an object in mapping [data] but this name is already used for a field in other types" }, "status": 400 } ] }的结果

curl -XGET localhost:9200/test3

脚本中有错字，应删除一个悬空的方括号

"inline": "... ctx._source['location.coordinates'] = ctx._source.templocation]; ctx._source.remove('templocation'); } "
                                                                             ^
                                                                             |
                                                                        remove this

Elasticsearch将动态映射的位置数据重新索引为几何形状
