allowNoIndices

@Nullable
public final Boolean allowNoIndices()

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.

API name: allow_no_indices

expandWildcards

public final List<ExpandWildcard> expandWildcards()

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.

API name: expand_wildcards

ignoreUnavailable

@Nullable
public final Boolean ignoreUnavailable()

If false, requests that include a missing data stream or index in the target indices or data streams return an error.

API name: ignore_unavailable

index

public final List<String> index()

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.

API name: index

masterTimeout

@Nullable
public final Time masterTimeout()

Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

API name: master_timeout

name

public final List<String> name()

Required - Comma-separated list of aliases to check. Supports wildcards (*).

API name: name
