Scroll API

We no longer recommend using the scroll API for deep pagination. If you need to preserve the index state while paging through more than 10,000 hits, use the search_after parameter with a point in time (PIT).

Retrieves the next batch of results for a scrolling search.

GET /_search/scroll
{
  "scroll_id" : "DXF1ZXJ5QW5kRmV0Y2gBAAAAAAAAAD4WYm9laVYtZndUQlNsdDcwakFMNjU1QQ=="
}

Request

GET /_search/scroll/<scroll_id> [7.0.0] Deprecated in 7.0.0.

GET /_search/scroll

POST /_search/scroll/<scroll_id> [7.0.0] Deprecated in 7.0.0.

POST /_search/scroll

Prerequisites

If the Elasticsearch security features are enabled, you must have the read index privilege for the target data stream, index, or alias.

Description

You can use the scroll API to retrieve large sets of results from a single scrolling search request.

The scroll API requires a scroll ID. To get a scroll ID, submit a search API request that includes an argument for the scroll query parameter. The scroll parameter indicates how long Elasticsearch should retain the search context for the request.

The search response returns a scroll ID in the _scroll_id response body parameter. You can then use the scroll ID with the scroll API to retrieve the next batch of results for the request. If the Elasticsearch security features are enabled, the access to the results of a specific scroll ID is restricted to the user or API key that submitted the search.

You can also use the scroll API to specify a new scroll parameter that extends or shortens the retention period for the search context.

See Scroll search results.

Results from a scrolling search reflect the state of the index at the time of the initial search request. Subsequent indexing or document changes only affect later search and scroll requests.

Path parameters

<scroll_id>: [7.0.0] Deprecated in 7.0.0. (Optional, string) Scroll ID of the search.

Scroll IDs can be long. We recommend only specifying scroll IDs using the scroll_id request body parameter.

Query parameters

scroll

(Optional, time value) Period to retain the search context for scrolling. See Scroll search results.

This value overrides the duration set by the original search API request’s scroll parameter.

By default, this value cannot exceed 1d (24 hours). You can change this limit using the search.max_keep_alive cluster-level setting.

You can also specify this value using the scroll request body parameter. If both parameters are specified, only the query parameter is used.

scroll_id

[7.0.0] Deprecated in 7.0.0. (Optional, string) Scroll ID for the search.

Scroll IDs can be long. We recommend only specifying scroll IDs using the scroll_id request body parameter.

rest_total_hits_as_int

(Optional, Boolean) If true, the API response’s hit.total property is returned as an integer. If false, the API response’s hit.total property is returned as an object. Defaults to false.

Request body

scroll

(Optional, time value) Period to retain the search context for scrolling. See Scroll search results.

This value overrides the duration set by the original search API request’s scroll parameter.

By default, this value cannot exceed 1d (24 hours). You can change this limit using the search.max_keep_alive cluster-level setting.

You can also specify this value using the scroll query parameter. If both parameters are specified, only the query parameter is used.

scroll_id: (Required, string) Scroll ID for the search.

Response body

The scroll API returns the same response body as the search API. See the search API’s response body parameters.
