Using script instead of a regex in aggs term filter include configuration

Elastic Stack Elasticsearch

Hello,

in the term aggregation it is possible to use the "include" to filter values with a regex.
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html#_filtering_values_4

{
	"from": 0,
	"size": 10,
	"query": {
		"match_all": {}
	},
	"aggs": {
		"title": {
			"terms": {
				"field": "title",
				"include": "t.*"
			}
		}
	}
  }

Is there a possibility to filter the values by a script instead of a regex?

If you really need script, you could use script query to filter docs, then use terms aggregation to aggregate on filtered docs.
