Question

我正在试图弄清楚是否可以对elasticsearch中的索引中的文档子集执行聚合。现在我正在玩这样的significant_terms聚合......

  "aggs" : {
    "aggs2" : {
      "filter": {
        "ids": {
          "values": [0, 1, 2, 3, 4, 5]
        }
      },
      "aggregations" : {
        "agg" : {
          "significant_terms" : {
            "field" : "contents"
          }
        }
      }
    }
  }

我可以限制执行聚合的文档吗？我正在查看过滤器聚合，但在尝试使用它时我会得到空桶。

  "aggregations": {
    "agg": {
      "doc_count": 6,
      "bg_count": 1111,
      "buckets": []
    }
  }

我可以这样做，如果是这样，身体的格式是什么？

由于

编辑：上面的例子和Val给我的例子给了我文件和一个空的聚合反应。

是的，您只需将过滤器添加到查询部分：
