SQL 쿼리를 elasticsearch로 변환하십시오.

Question

이 쿼리를 탄성 검색으로 변환해야하지만 탄성 검색에서 (having)은 아직 지원되지 않습니다. 여기

`GET /analytics_data/_search 
{ 
"size": 0, 
"query": { 
    "bool": { 
"filter": [ 
     { 
      "term": 
      { 
      "field": "test" 
      } 
     } 
     ] 
    } 
}, 
"aggs": { 
    "aggregation": { 
     "terms": { 
     "field": "prop1" 
    }, 
    "aggs": { 
     "subaggregation": { 
     "terms": { 
      "field": "prop2", 
      "order": { 
      "_count": "desc" 
      } 
      } 
      }, 
     "test":{ 
     "bucket_selector": { 
      "buckets_path": 
      { 
      "test1": "_count" 
      }, 
      "script":"params.test1 == 1" 
     } 
     } 
     } 
     } 
    } 
    }` 

내가 사용하는 매핑 :

PUT /index 
{ 
    "mappings" : { 
     "timeline" : { 
      "properties" : { 
       "prop1" : { 
        "type" : "keyword" 
       }, 
       "prop2" : { 
        "type" : "keyword"       
       } 
      } 
     } 
    } 
} 

을하지만 내가 가지고있는 하위 집계 버킷을 얻을 수

Select sum(count) as count,prop1 from ( SELECT Count(*) as count,prop1 FROM [table1] group by prop1,prop2 having count = 1 ) group by prop1 order by count desc limit 10

나는 탄성 검색이 쿼리를 시도 개수 == 1

시도해보십시오. 집계 final은 원하는 결과를 제공합니다.

GET /analytics_data/_search 
{ 
    "size": 0, 
    "query": { 
    "bool": { 
     "filter": [ 
     { 
      "term": { 
      "field": "test" 
      } 
     } 
     ] 
    } 
    }, 
    "aggs": { 
    "prop1": { 
     "terms": { 
     "field": "prop1", 
     "size": 10 
     }, 
     "aggs": { 
     "prop2": {

근무 코드 :
