// Always use try-with-resources for ResponseData
try (ResponseData responseData = client.execute(requestData)) {
    // Process
}  // Temp files auto-deleted

        } finally {
            // Cleanup
            try {
                client.admin().indices().prepareDelete(suggester.getIndex() + "*").execute().actionGet();
