                        "type" : "string"
                    }
                }
            }
        }
    }
  }

}

我的问题是使用此聚合搜索产品

{
 "aggs" : {
    "product" : {
     "nested" : {
            "path" : "properties"
        },

        "aggs" : {
            "id" : {
                "terms" : {
                    "field" : "doc.properties.name.ersoy"
                }
            }
        }
    }
}

}

我收到此错误。

 {
   "error": "SearchPhaseExecutionException[Failed to execute phase  
 [query_fetch], all shards failed; shardFailures {[bFRHdmHASWCZPk-tbyg4Zw]  [elastic-products1][0]: AggregationExecutionException[[nested] nested path [properties] not found]}]",
    "status": 500
  }

我错了，我看不到。任何人都可以帮助我

请尝试使用此查询，您需要在嵌套路径中使用"doc.properties"，而不仅仅是"properties"

{
 "aggs" : {
    "product" : {
     "nested" : {
            "path" : "doc.properties"       <---- fix this line
        },

        "aggs" : {
            "id" : {
                "terms" : {
                    "field" : "doc.properties.name.ersoy"
                }
            }
        }
    }
}
