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.

In Elastic Cloud Serverless, the default refresh interval is 5 seconds across all indices.

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()
      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.

      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, 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.

      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

    • rebuild

      public RefreshRequest.Builder rebuild()
      Returns:
      New RefreshRequest.Builder initialized with field values of this instance
