Get aliases

GET /{index}/_alias

Retrieves information for one or more data stream or index aliases.

Path parameters

  • index string | array[string] Required

    Comma-separated list of data streams or indices used to limit the request. Supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

Query parameters

  • allow_no_indices boolean

    If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices.

  • expand_wildcards string | array[string]

    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. Valid values are: all, open, closed, hidden, none.

  • ignore_unavailable boolean

    If false, the request returns an error if it targets a missing or closed index.

          • routing string

            Value used to route indexing and search operations to a specific shard.

          • search_routing string

            Value used to route search operations to a specific shard. If specified, this overwrites the routing value for search operations.
