如何在Elasticsearch 5.1中检索字段以及聚合函数（使用curl）？

Answer 1

You can use aggregations for that, like this:

curl -XPOST localhost:9200/abc -d '{
  "_source": ["x", "y"],
  "aggs": {
    "group_by_x" : {
      "terms": {
        "field": "x"
      },
      "aggs": {
        "group_by_y": {
          "terms": {
            "field": "y"
          }
        }
      }
    }
  }
}'
