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'"United States",33755"Charities--Massachusetts",8304"Almshouses--Massachusetts--Tewksbury",8304"Shields",4232"Coat of arms",4214"Springfield College",3422"Men",3136"Trees",3086"Session Laws--Massachusetts",2668"baseball players",2543"Animals",2527"Books",2119"Women",2004"Landscape",1940"Floral",1821"Architecture, Domestic--Lowell (Mass)--History",1785"Parks",1745"Buildings",1730"Houses",1611"Snow",1579
