Get the search shards

POST also GET /{index}/_search_shards
POST also GET /_search_shards

Get the indices and shards that a search request would be run against. This information can be useful for working out issues or planning optimizations with routing and shard preferences. When filtered aliases are used, the filter is returned as part of the indices section.

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

Required authorization

Index privileges: view_index_metadata

Path Parameters

index union IndexName | [] IndexName optional

A comma-separated list of data streams, indices, and aliases to search. It supports wildcards (*). To search all data streams and indices, omit this parameter or use * or _all.

Leave it out to use /_search_shards.

Query Parameters

allow_no_indices boolean · default: false

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

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.

local boolean · default: false

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

master_timeout string Duration · default: 30s

The period to wait for a connection to the master node. If the master node is not available before the timeout expires, the request fails and returns an error. IT can also be set to -1 to indicate that the request should never timeout.

preference string

The node or shard the operation should be performed on. It is random by default.

routing union Routing

A custom value used to route operations to a specific shard. Not allowed when index.slice.enabled is true for the target index; use _slice instead.

One of: string or string[]
