elasticsearch - Elasticsearch找不到geo_point字段，如何正确添加到字段的映射？

Question

这是我来自http://localhost:9200/fb_events/_search的示例结果

    [...]
    "hits": {
    "total": 18,
    "max_score": 1,
    "hits": [
    {
    "_index": "fb_events",
    "_type": "event",
    "_id": "AVw1MpQDmr08c_VMq0b_",
    "_score": 1,
    "_source": {
    "description": "desc",
    "start_time": "2017-11-17T20:00:00+0100",
    "place": {
    "id": "496893413669851",
    "name": "Dwa Światy",
    "location": {
    "city": "Torun",
    "zip": "87-100",
    "country": "Poland",
    "longitude": 18.603430234931,
    "street": "ul. Ducha św. 10/12",
    "latitude": 53.009319027091,
    "geo_cord": "18.6034302349,53.0093190271"
    }
    },
    "end_time": "2017-11-17T23:00:00+0100",
    "id": "622266071285763",
    "name": "Podwórkowi Chuligani (XX-lecie) + TBA - Toruń / Dwa Światy"
    }
    }
}
[...]

我想根据位置搜索记录。这是我的查询:

 query = {
        "size": 100,
        "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter": {"geo_distance": {"distance": distance, "geo_cord": {"lat": lat, "lon": lon}}}
        }
      }
    }

但是当我执行此操作时，出现错误RequestError: TransportError(400, u'search_phase_execution_exception', u'failed to find geo_point field [geo_cord]')
我的问题是，我该怎么办？将映射添加到此字段？

编辑:

Answer 1

根据您的映射，geo_cord字段的类型为text，但如果要在geo_point查询中使用它，则应为geo_distance。

在索引第一个文档之前，您需要删除索引并使用正确的映射重新创建索引。

并确保在查询中使用place.location.geo_cord而不是location.geo_cord。
