_bucket_count 在 bucket_selector- 管道聚合中

Question

我正在努力完成这项工作，但运气不佳。这种语法应该有效吗？我指的是这个 git 问题： https://github.com/elastic/elasticsearch/pull/19571

谢谢！

试试这个：

{
  "size": 0,
  "aggs": {
    "groupby_country": {
      "terms": {
        "field": "country",
        "size": 2000
      },
      "aggs": {
        "should_we_consider": {
          "bucket_selector": {
            "buckets_path": {
              "hits": "groupby_domain._bucket_count"
            },
            "script": "params.hits > 0"
          }
        },
        "groupby_domain": {
          "terms": {
            "field": "domain",
            "size": 2000
          },
          "aggs": {
            "groupby_page": {
              "terms": {
                "field": "page",
                "size": 2000,
                "min_doc_count": 2
              }
            }
          }
        }
      }
    }
  }
}
