| Use `geotile_grid` sources to aggregate `geo_point` values into buckets representing map tiles. As with the other composite aggregation `sources`, by default results include only buckets that contain data. | ||
|
|
||
| Each cell corresponds to a [map tile](https://en.wikipedia.org/wiki/Tiled_web_map). Cell labels use a "{zoom}/{x}/{y}" format. |

Is there a site that does a good job of explaining the x,y system that geo-grid uses?
Does OpenSearch use one of the available geo-grid standards?

| Use the `date_histogram` to create composite aggregations of date ranges. | ||
|
|
||
| OpenSearch represents dates, including `date_interval` bucket keys, as `long` integers representing [milliseconds since epoch](https://en.wikipedia.org/wiki/Unix_time). You can output a date format instead using the `format` parameter. This does not change the key order. |

Please confirm that the key order does not change. Key order is based on the INT64 value, correct?

| ## Paginating composite results |
There was a problem hiding this comment.
How long are results cached for display pagination?
Are there any shortcuts to displaying result pages, or do you have to give it the entire request plus after parameter each time?

| # Composite aggregations |
There was a problem hiding this comment.
There does not seem to be any mention of index sorting in OpenSearch. Is it possible to speed up composite searches on large datasets by sorting an index? If so, is this a common enough use case to mention on this page?
Description
Add a page for composite aggregations. Includes examples for all 4 source types, combining source types, sub-aggregations, and pagination.
