use of org.elasticsearch.action.search.ShardSearchFailure in project metron by apache.

     * shard failures are only logged.  the search itself is not failed.  this approach
     * assumes that a user is interested in partial search results, even if the
     * entire search result set cannot be produced.
     *
     * for example, assume the user adds an additional sensor and the telemetry
     * is indexed into a new search index.  if that search index is misconfigured,
     * it can result in partial shard failures.  rather than failing the entire search,
     * we log the error and allow the results to be returned from shards that
     * are correctly configured.
