You might be running into this bug [Slow StringTermsAggregatorFromFilters · Issue #76104 · elastic/elasticsearch (github.com)](https://github.com/elastic/elasticsearch/issues/76104) in 7.13.x, which was fixed in 7.14.0.

You can see if this is the case, by using the issues provided workaround, setting the following cluster setting:

```json
"search.aggs.rewrite_to_filter_by_filter": false

```

I ran into a fairly similar issue not too long ago with a somewhat simple agg, and this turned out to be the issue.

But as mentioned previously, being able to see the query and agg you're actually running would be helpful here.
