public class ClearCacheRequest extends RequestBase
Clear the cache.

Clear the cache of one or more indices. For data streams, the API clears the caches of the stream's backing indices.

By default, the clear cache API clears all caches. To clear only specific caches, use the fielddata, query, or request parameters. To clear the cache only of specific fields, use the fields parameter.

    • 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

    • fielddata

      @Nullable public final Boolean fielddata()
      If true, clears the fields cache. Use the fields parameter to clear the cache of specific fields only.

      API name: fielddata

    • fields

      public final List<String> fields()
      Comma-separated list of field names used to limit the fielddata parameter.

      API name: fields

    • 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

    • query

      @Nullable public final Boolean query()
      If true, clears the query cache.

      API name: query

    • request

      @Nullable public final Boolean request()
      If true, clears the request cache.

      API name: request

    • rebuild

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