node.js - 如何在elasticsearch中对地理坐标应用过滤器？

Question

我正在将elasticsearch与mongoosastic npm模块一起使用。我正在尝试对具有以下模型结构的地理坐标应用过滤器

geoLocation: {
    type: {
      type: String,
      default: 'Point'
    },
    coordinates: [Number] //orders should be lat,lng
  }

映射如下

{
      "events": {
        "settings": {
          "analysis": {
            "filter": {
              "edgeNGram_filter": {
                "type": "edgeNGram",
                "min_gram": 1,
                "max_gram": 50,
                "side": "front"
              }
            },
            "analyzer": {
              "edge_nGram_analyzer": {
                "type": "custom",
                "tokenizer": "edge_ngram_tokenizer",
                "filter": [
                  "lowercase",
                  "asciifolding",
                  "edgeNGram_filter"
                ]
              },
              "whitespace_analyzer": {
                "type": "custom",
                "tokenizer": "whitespace",
                "filter": [
                  "lowercase",
                  "asciifolding"
                ]
              }
            },
            "tokenizer": {
              "edge_ngram_tokenizer": {
                "type": "edgeNGram",
                "min_gram": "1",
                "max_gram": "50",
                "token_chars": [
                  "letter",
                  "digit"
                ]
              }
            }
          }
        },
        "mappings": {
          "event": {
            "_all": {
              "index_analyzer": "nGram_analyzer",
              "search_analyzer": "whitespace_analyzer"
            },
            "properties": {
              "title": {
                "type": "string",
                "index": "not_analyzed"
              },
              "geoLocation": {
                "index": "not_analyzed",
                "type": "geo_point"
              }
            }
          }
        }
      }
    }

查询

{
        "query": {
          "multi_match": {
            "query": "the",
            "fields": ["title", ]
          }
        },
        "filter" : {
            "geo_distance" : {
                "distance" : "200km",
                "geoLocation.coordinates" : {
                    "lat" : 19.007452,
                    "lon" : 72.831556
                }
            }
        }
      }

我无法使用以下模型结构在地理坐标上创建索引，我不明白是否无法使用上述模型结构对地理坐标进行索引，因为在我的情况下，坐标的顺序为纬度、经度和我发现elasticsearch期望坐标顺序为long,lat。

错误

我的问题得到了解决

映射

放置/geo_test

{
   "mappings": {
      "type_test": {
         "properties": {
            "name": {
               "type": "string"
            },
            "geoLocation": {
               "type": "nested",
               "properties": {
