[ElasticSearch]: Get all indices containing a specific value - elasticsearch

Question

Following is the use case:
I am trying to list all indices in elasticsearch that contain a particular value.
For illustration purposes let us consider following to be the index template:
{
"order": 0,
"template": "sample-*",
"settings": {
"index.refresh_interval": "300",
"index.number_of_replicas": "1",
"index.number_of_shards": "10"
},
"mappings": {
"digital": {
"_source": {
"enabled": false
},
"_all": {
"enabled": false
},
"properties": {
"website": {
"index": "not_analyzed",
"store": false,
"type": "string",
"doc_values": true
},
"iab_codes": {
"store": false,
"type": "long",
"doc_values": true
},
"audiences": {
"store": false,
"type": "long",
"doc_values": true
}
}
}
},
"aliases": {
}
}
The audiences field in this template is a sequence of long eg. [1,2,3]. I create one index per day based on this template. How can I get the list of all the indices that contain a specific value in the audiences array field.
Something like list all the indices where audience array contains the value 3.
Thank you.

You can make a search query similar to
http://localhost:9200/sample-*/_search?q=audiences:3&pretty
and using the Java API, you can try getting the value of hits.hits._index
Or rather use filter_path :
http://localhost:9200/sample*/_search?q=audiences:3&filter_path=hits.hits._index&pretty
Result will look like this
