Aggregation

An aggregation summarizes your data as metrics, statistics, or other analytics. Aggregations help you answer questions like:

• What’s the average load time for my website?
• Who are my most valuable customers based on transaction volume?
• What would be considered a large file on my network?
• How many products are in each product category?

A sample search

.. literalinclude:: sample.php
   :language: php
   :linenos:

Return only aggregation results

By default, searches containing an aggregation return both search hits and aggregation results. To return only aggregation results, set size to 0.

.. literalinclude:: size_result.php
   :language: php

Run multiple aggregations

You can use multiple aggregations in the same request.

.. literalinclude:: multiple_aggregations.php
   :language: php
   :linenos:

Run sub-aggregations

Bucket aggregations support bucket or metric sub-aggregations. There is no level or depth limit for nesting sub-aggregations.
