我已经使用cURL和jq（“ likesed，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'
