Terms Aggregation Restricted to Top Matches?

Elastic Stack Elasticsearch
1

Hi,

Is it possible to do a Terms aggregation in Elasticsearch, but restricted
to the top N matching documents?
I'm aware of the top_hits aggregator, but it does not allow sub
aggregations.
So while I can get the top N matches per term, I can't find a way to get
the terms of the top N matches.

My current query is something like:

GET /myindex/mydoc/_search
{
"size": 0,
"query": {"match": {
"field_to_search": "some search string"
}}
,"aggs": {
"term_aggregation": {
"terms": {
"field": "Tags",
"size": 0,
"order": {
"summed_score": "desc"
}
},
"aggs":{"summed_score":{"sum":{"script":"doc.score"}} }
}
}
}

which aggregates the scores of ALL matching documents by terms in the Tags
field.

Is there any way to do what I want?

Thanks
