Suspicious referee report, are "suggested citations" from a paper mill? The bucket terms 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. @nknize My use case, I've renamed fields but still have a need to build visualizations around the data. Asking for help, clarification, or responding to other answers. There are different mechanisms by which terms aggregations can be executed: Elasticsearch tries to have sensible defaults so this is something that generally doesnt need to be configured.

For example, if you have two fields f and g, you can run a terms aggregation on the union of the values of these fields by running the following aggregation (it works with both groovy and mvel): It might not be very performant, so if you plan on running a terms aggregation on several fields on a regular basis, you might want to use the copy_to directive in your mappings in order to copy field values to a dedicated field at indexing time and use this field to run the aggregations: The reason why we're not planning on supporting this directly is that it would be much slower and heavier than a normal terms aggregation. my-field: Aggregation results are in the responses aggregations object: Use the query parameter to limit the documents on which an aggregation runs: By default, searches containing an aggregation return both search hits and The aggregations API allows grouping by multiple fields, using sub-aggregations. values are "allowed" to be aggregated, while the exclude determines the values that should not be aggregated.
