elasticsearch - 嵌套过滤器在Elasticsearch 1.7中无法正常工作

Question

我不能使nested_filter排序正常工作。
我有这样的映射-

"metadata": {
      "type": "nested",
      "include_in_parent": true,
      "properties": {
        "property": {
          "type": "string",
          "index" : "not_analyzed",
          "include_in_parent" : false,
          "include_in_all" : false
        },
        "type": {
          "type": "string",
          "index": "not_analyzed"
        },
        "value": {
          "type": "string",
          "fields": {
            "lower_case_sort": {
              "type": "string",
              "analyzer": "case_insensitive_sort"
            }
          }
        }
      }
    },

因此，每个文件都有元数据，其属性为“duration”，值的持续时间值例如为50.300。
这里有我要查询的查询，但它不返回升序或降序的结果，它是随机的。

  "query": {
    "bool": {
      "must": {
          "term" : {
                "parent.raw": "folderName"
           }
      }
    }
  },
  "size": 50,
  "from": 0,
  "sort": {
        "metadata.value": {
            "order":"desc",
            "nested_filter": {
                "term": { "metadata.property":"duration" }
            }
        }
    }
}

What could be the issue?

Thank you!

The nested_path and nested_filter options have been deprecated infavor of the options documented above 6.1.

在下面的搜索查询中尝试一下

{
  "query": {
    "bool": {
      "must": {
        "term": {
          "parent.raw": "folderName"
        }
      }
    }
  },
  "sort": [
    {
      "metadata.value": {
        "order": "asc",
        "nested": {
          "path": "metadata",
          "filter": {
            "term": {
              "metadata.property": "duration"
            }
          }
        }
      }
    }
  ]
}
