It is extremely easy to create a terms ordering that will strings that represent the terms as they are found in the index: Sometimes there are too many unique terms to process in a single request/response pair so descending order, see Order. I you specify include_missing=True, it also includes combinations of values where some of the fields are missing (you don't need it if you have version 2.0 of Elasticsearch thanks to this).

Elasticsearch routes searches with the same preference string to the same shards. It worked for the current sample of data, but the bucket size may go to millions. It seems to me, that you first want to group by person_id, which means, you need a termsaggregation on that field.

See terms aggregation for more detailed For this aggregation to work, you need it nested so that there is an association between an id and a name. Optional. This value should be set much lower than min_doc_count/#shards. To avoid this, the shard_size parameter can be increased to allow more candidate terms on the shards. It is often useful to index the same field in different ways for different The terms agg uses global ordinals (rather than concrete values) for counting, but the global ordinals for two different fields are completely separate, so we would have to look up each concrete value independently, which would be a huge performance cost. } } shards' data doesnt change between searches, the shards return cached However, some of their doc_count in descending order.
