Question

我是ES的新手。我正在尝试编写java程序来使用ES对MongoDB进行geosearch（安装了河流插件等，并且能够使用java程序进行正常搜索）。我在mongodb中有一个集合（表），其中存储了latitide和经度值。现在我想根据我从Java程序传递的lat和long来检索记录。

    FilterBuilder filter =  FilterBuilders.geoDistanceFilter("pin.location").lat(10).lon(20).distance(5,DistanceUnit.KILOMETERS).geoDistance(GeoDistance.PLANE);

    SearchResponse response = client.prepareSearch(INDEX)
                                    .setTypes(TYPE)
                                    .setSearchType(SearchType.QUERY_AND_FETCH)
                                    .setQuery(matchAllQuery())
                                    .setPostFilter(filter)
                                    .setFrom(0).setSize(60).setExplain(true)
                                    .execute()
                                    .actionGet();

如果我执行上述程序，我会得到＆＃34; QueryParsingException [[mongoindex]无法找到geo_point字段[pin.location]];＆＃34; 这个pin.location是什么？我的mongodb表也有专栏“Latitude＆＃34;和经度＆＃39;。但是在上面的过滤器中我有'lat（10）.lon（20）＆＃39;。我在这里遗漏了一些东西。请帮我理解。任何快速帮助高度赞赏。

Answer 1

您正在创建的过滤器基于字段pin.location

FilterBuilders.geoDistanceFilter("pin.location")

这回答了你关于这个pin.location的问题。开始查看索引的映射，以查看要添加到elasticsearch的字段是否为 geo_point 类型。我自己没有使用过mongo河，但根据这个问题，你必须提供自己的地图。

https://github.com/richardwilly98/elasticsearch-river-mongodb/issues/218#issuecomment-35824681

以下上述帖子的示例：

curl -XPUT 'http://localhost:9200/location_test' -d '
{
    "mappings": {
        "places": {
            "properties": {
               "location": {
                    "type": "geo_point"
                }
            }
        }
    }
}
'

有关elasticsearch中geo_point的更多信息，请访问： http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-geo-point-type.html

感谢您提供的信息。问题已解决。使用以下配置工作正常。

curl -XPUT 'http://localhost:9200/myindex' -d '
{
   "settings" : {
        "number_of_shards" : 2,
        "number_of_replicas" : 1
    },
   "mappings" : {
      "my_details" : {
          "properties" : {
              "my_id" : {"type" : "integer", "store" : "yes" , "index":"not_analyzed"},
              "location" : {"type" : "geo_point", "store" : "yes", "index":"not_analyzed"}
          }
      }
  }

}'

curl -XPUT 'http://localhost:9200/_river/my_river/_meta' -d '
{
    "type": "mongodb",
    "mongodb": {
        "db": "MyDatabase",
        "collection": "my_details"
    },
    "index": {
        "name": "myindex",
        "type": "my_details"
    }

}'

注意：MongoDb有＆＃39; my_details＆＃39;收集在＆＃39; MyDatabase＆＃39; 干杯， Cdhar
