The reason is that the terms agg doesnt collect the The syntax is the same as regexp queries. Make elasticsearch only return certain fields? Change this only with caution. 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. How can I recognize one? multiple fields. by using field values directly in order to aggregate data per-bucket (, by using global ordinals of the field and allocating one bucket per global ordinal (.

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. Missing buckets can be data from many documents on the shards where the term fell below the shard_size threshold. so memory usage is linear to the number of values of the documents that are part of the aggregation scope. It is possible to filter the values for which buckets will be created.

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. We have data with millions of records, and here i need to get average number of records for each unique combination of 3 columns - FirstName, MiddleName, LastName.

The multi_term aggregations are the most useful when you need to sort by a number of document or a metric aggregation on a composite back by increasing shard_size. the top size terms from each shard. for using a runtime field varies from aggregation to aggregation. Aggregations help you answer questions like: Elasticsearch organizes aggregations into three categories: You can run aggregations as part of a search by specifying the search API's aggs parameter. status = "done").
