node.js - Elasticsearch搜索解析异常，但返回结果

Question

我将ELasticsearch和Meteor.js与npm / elasticsearch插件一起使用，将ES与Meteor一起使用。
这是我的查询:

search = {
"body": {
  "aggs": {
    "traces": {
      "filter": {
        "and": [
          {
            "range": {
              "date": {
                "gte": "2015-01-31T23:00:00.000Z",
                "lte": "2015-10-02T21:59:59.000Z"
              }
            }
          },
          {
            "geo_bounding_box": {
              "loc.coordinates": {
                "top_left": {
                  "lat": 51.767839887322154,
                  "lon": -9.404296875
                },
                "bottom_right": {
                  "lat": 40.96330795307353,
                  "lon": 14.326171874999998
                }
              }
            }
          },
          {
            "or": [
              {
                "and": [
                  {
                    "term": {
                      "geoip": false
                    }
                  },
                  {
                    "term": {
                      "trackerId": "RG-000000010-1"
                    }
                  }
                ]
              }
            ]
          }
        ]
      },
      "aggs": {
        "trackerId": {
          "terms": {
            "field": "trackerId",
            "size": 0
          },
          "aggs": {
            "heatmap": {
              "geohash_grid": {
                "field": "loc.coordinates",
                "precision": 6
              }
            }
          }
        }
      }
    }
  }
 }
}

我用esClient.search(search)发送它并收到异常(exception)的答案，但是ES抛出此错误:

显然，它找不到geo_point字段类型。

这是我映射的启示部分:

{
            'trace': {
                'properties': {
                    'loc': {
                        'type': 'object',
                        'properties': {
                            'type': {
                                'type': 'string'
                            },
                            'coordinates':{
                                'type': 'geo_point',
                                'geohash':true,
                                'geohash_prefix':true,
                                'lat_lon':true,
                                'fielddata' : {
                                    'format' : 'compressed',
                                    'precision' : '1cm'
                                }
                            }
                        }
                    }
    ...

那么为什么找不到geo_point类型呢？

Answer 1

您需要将查询发送到包含trace类型文档的索引。如果将查询发送到根端点/(如果未指定，则为默认值)，则将查询所有索引。在您的情况下，此操作失败，因为.marvel-2015.10.02索引没有名为geo_point的loc.coordinates字段。

因此，您的通话应如下所示:

var search = {
    index: "your_index",             <--- add this
    body: {...}
};
esClient.search(search);
