Elasticsearch – Apply Nested Filter on Nested (Inner) Aggregation

           The following query can be used to apply filter on nested (inner) aggregation. In our example aggregationName2 is the nested aggregation. The filter (bold content) in the input JSON will be applied only for the aggregation aggregationName2. aggregationName2 takes in the output of aggregationName1, then applies the filter which is then processed by aggregationName2 for the final results.

 

GET /index/type/_search
{
    "aggs": {
        "aggregationName1": {
            "terms": {
                "field": "fieldName1"
             },
             "aggs": {
                 "filtered": {
                     "filter": {
                         "bool": {
                             "must": [{
                                 "term": {
                                     "filterFieldName": filterFieldValue
                                  }
                             }]
                         }
                     },
                     "aggs": {
                         "aggregationName2": {
                             "terms": {
                                 "field": "fieldName2"
                             }
                         }
                     }
                 }
             }
         }
    },   
    "size": 0
