23.03.2021 · A multi-bucket value source based aggregation where buckets are dynamically built - one per unique set of values. The multi terms aggregation is very similar to the terms aggregation, however in most cases it will be slower than the terms aggregation and will consume more memory.Therefore, if the same set of fields is constantly used, it would be …
Elasticsearch organizes aggregations into three categories: Metric aggregations that calculate metrics, such as a sum or average, from field values. Bucket aggregations that group documents into buckets, also called bins, based on field values, ranges, or other criteria.

13.08.2020 · A multi-bucket aggregation that creates composite buckets from different sources. Unlike the other multi-bucket aggregations, you can use the composite aggregation to paginate all buckets from a multi-level aggregation efficiently. This aggregation provides a way to stream all buckets of a specific aggregation, similar to what scroll does for documents.
By default, Elasticsearch does all aggregations in a single pass. For example, if you had a terms aggregation and a cardinality aggregation nested in it, Elasticsearch would make a bucket for each term, calculate the cardinality for each bucket, sort those buckets, and return the top X.
12.02.2014 · Multi-field support would be nice for other aggregations as well, especially for statistical ones such as avg. An example would be to calculate an average across multiple fields. Currently we have to compute the sum and count for each field and do the calculation ourselves.
13.08.2020 · You can aggregate on this single field, which will benefit from the global ordinals optimization. multi_terms aggregation Use multi_terms aggregation to combine terms from multiple fields into a compound key. This also disables the global ordinals and will be slower than collecting terms from a single field.
Limit the scope by filtering documents out · Experiment with different sharding settings · Evaluate high-cardinality fields and global ordinals · Increase refresh ...
I have explored how to accomplish this, the solutions seem to be: Combine the fields when indexing. A script to munge together the fields. A nested aggregation. Option one and two are are not available to me so I have been going with 3 but it's not responding in an expected manner. Given the following query (still searching for documents also ...
