如何清除ElasticSearch索引？

找到的解决方案：

IndicesAdminClient adminClient = searchConnection.client.admin().indices();String indexName = "location";DeleteIndexResponse delete = adminClient.delete(new DeleteIndexRequest(indexName)).actionGet()if (!delete.isAcknowledged()) {    log.error("Index {} wasn't deleted", indexName);}

和

client.admin().indices().flush(new FlushRequest('location')).actionGet();

将新数据放入索引后。
