我喜欢根据位置搜索记录。这是我的问题：

 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，我收到错误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？添加映射到此字段？

编辑：

GET /fb_events/_mapping/event

的输出

Answer 1

根据您的映射，geo_cord字段的类型为text，如果您想在geo_point查询中使用它，则该字段应为geo_distance。< / p>

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代替location.geo_cord。

Elasticsearch无法找到geo_point字段，如何更正向域添加映射？
