我已经使用cURL和jq（“ like
sed，但对于JSON”）完成了此操作。例如，您可以执行以下操作以获取给定构面的前20个值的CSV输出：

$ curl -X GET 'http://localhost:9200/myindex/item/_search?from=0&size=0' -d '
    {"from": 0,
    "size": 0,
    "facets": {
      "sourceResource.subject.name": {
        "global": true,
        "terms": {
          "order": "count",
          "size": 20,
          "all_terms": true,
          "field": "sourceResource.subject.name.not_analyzed"
        }
      }
    },
    "sort": [
      {
        "_score": "desc"
      }
    ],
    "query": {
      "filtered": {
        "query": {
          "match_all": {}
        }
      }
    }
  }' | jq -r '.facets["subject"].terms[] | [.term, .count] | @csv'
