ElasticSearch DSL聚合

字段聚合:	DSL: { "aggs": { "all_course": { "terms": { "field": "golf_course_id" } } } } 结果: {     "aggregations": {         "all_course": {             "doc_count_error_upper_bound": 734,             "sum_other_doc_count": 190883,             "buckets": [                 { "key": 183, "doc_count": 1629 },                 { "key": 3, "doc_count": 1055 }             ]         }     } }
聚合后汇总计算	DSL: { "aggs": { "all_course": { "terms": { "field": "golf_course_id" }, "aggs": { "avg_prepay_price": { "avg": { "field": "prepay_price" } } } } } } 结果: { "aggregations": { "all_course": { "doc_count_error_upper_bound": 734, "sum_other_doc_count": 190883, "buckets": [ { "key": 183, "doc_count": 1629, "avg_age": { "value": 575.7667280540209 } }, { "key": 3, "doc_count": 1055, "avg_age": { "value": 831.0710900473933 } } ] } } }
