How can I filter the doc_count value which is a result of a nested aggregation? Here is my query:
"aggs": {
"CDIDs": {
"terms": {
"field": "CDID.keyword",
"size": 1000
},
"aggs": {
"my_filter": {
"filter": {
"range": {
"transactionDate": {
"gte": "now-1M/M"
}
}
}
},
"in_active": {
"bucket_selector": {
"buckets_path": {
"doc_count": "_count"
},
"script": "params.doc_count > 4"
}
}
}
}
}
The result of the query looks like:
{
"aggregations" : {
"CDIDs" : {
"doc_count_error_upper_bound" : 0,
"sum_other_doc_count" : 2386,
"buckets" : [
{
"key" : "1234567",
"doc_count" : 5,
"my_filter" : {
"doc_count" : 4
}
},
{
"key" : "12345",
"doc_count" : 5,
"my_filter" : {
"doc_count" : 5
}
}
]
}
}
}
I'm trying to filter the second doc_count value here. Let's say I wanna have docs that are > 4 so the result should be having only one aggregation result in a bucket with doc_count = 5. Can anyone help how can I do this filter? Please let me know if any additional information is required.
Take a close look at the bucket_selector aggregation. You simply need to specify the aggregation name in buckets_path
section i.e. "doc_count":
"my_filter>_count"
Pipeline aggregation (buckets_path) has its own syntax where >
acts as a separator. Refer to this LINK for more information on this.
