Sub agg depending on length of results

Elastic Stack Elasticsearch
1

Hello. I have several fields, and I want to put each one as a sub agg of another one.

Say A->subAgg(B)->subAgg(C)->subAgg(D)

But I want them to be put depending on their number of results. If for example D has the most results as an aggregation I want it to be put at first, and the next one is the one containing the second most results, say A... etc like so D->subAgg(A)->subAgg(B)->subAgg(C)

How can I do that?

Afraid that isn't possible. Order of the aggregation in the tree determines which and how documents match the child sub-aggregations. We can't reorder the aggs predominantly for technical reasons, but also because it would break the counts and metrics. The generated counts/metrics are only valid in the order specified.

What are you trying to accomplish?
