Class RefreshRequest

co.elastic.clients.elasticsearch._types.RequestBase

co.elastic.clients.elasticsearch.indices.RefreshRequest

public class RefreshRequest
extends RequestBase

Refresh an index. A refresh makes recent operations performed on one or more indices available for search. For data streams, the API runs the refresh operation on the stream’s backing indices.

By default, Elasticsearch periodically refreshes indices every second, but only on indices that have received one search request or more in the last 30 seconds. You can change this default interval with the index.refresh_interval setting.

Refresh requests are synchronous and do not return a response until the refresh operation completes.

Refreshes are resource-intensive. To ensure good cluster performance, it's recommended to wait for Elasticsearch's periodic refresh rather than performing an explicit refresh when possible.

If your application workflow indexes documents and then runs a search to retrieve the indexed document, it's recommended to use the index API's refresh=wait_for query parameter option. This option ensures the indexing operation waits for a periodic refresh before running the search.

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

API name: expand_wildcards

ignoreUnavailable

@Nullable
public final Boolean ignoreUnavailable()

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

API name: ignore_unavailable

index

public final List<String> index()

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

API name: index
