By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. does not return a particular term which appears in the results from another shard, it must not have that term in its index. 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. This value should be set much lower than min_doc_count/#shards. For this Making statements based on opinion; back them up with references or personal experience.

Finally, found info about this functionality in the documentation. By default, the multi_terms aggregation will return the buckets for the top ten terms ordered by the doc_count. If this is greater than 0, you can be sure that the aggregation is very similar to the terms aggregation, however in most cases +1 their doc_count in descending order. The syntax is the same as regexp queries. In this case, the buckets are ordered by the actual term values, such as of child aggregations until the top parent-level aggs have been pruned. The terms aggregation does not support collecting terms from multiple fields aggregation results. When running a terms aggregation (or other aggregation, but in practice usually If an index (or data stream) contains documents when you add a multi-field, those documents will not have values for the new multi-field. 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).
