Use the size parameter to return more terms, up to the search.max_buckets limit. results: sorting by a maximum in descending order, or sorting by a minimum in I have tried to mitigate this by adding an exclude to the nested aggregation but this slowed the query down far too much (around 100 times for 500000 docs). Or other case: the metadata names are auto generated and I would like to get terms aggregations for all of them. shard_min_doc_count is set to 0 per default and has no effect unless you explicitly set it.
