Check indices

HEAD /{index}

Check if one or more indices, index aliases, or data streams exist.

Path Parameters

index union IndexName | [] IndexName required: Comma-separated list of data streams, indices, and aliases. Supports wildcards (*).

Query Parameters

allow_no_indices boolean · default: true

A setting that does two separate checks on the index expression. If false, the request returns an error (1) if any wildcard expression (including _all and *) resolves to zero matching indices or (2) if the complete set of resolved indices, aliases or data streams is empty after all expressions are evaluated. If true, index expressions that resolve to no indices are allowed and the request returns an empty result.

expand_wildcards string ExpandWildcards · default: open

Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden.

Supported values include:

all: Match any data stream or index, including hidden ones.
open: Match open, non-hidden indices. Also matches any non-hidden data stream.
closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
none: Wildcard expressions are not accepted.

Values: all open closed hidden none

flat_settings boolean · default: false

If true, returns settings in flat format.

ignore_unavailable boolean · default: false

If false, the request returns an error if it targets a concrete (non-wildcarded) index, alias, or data stream that is missing, closed, or otherwise unavailable. If true, unavailable concrete targets are silently ignored.

include_defaults boolean · default: false

If true, return all default settings in the response.

local boolean · default: false

If true, the request retrieves information from the local node only.
