" }}我们查看 test_reindexed 的内容:GET test_reindexed/_doc/1从上面的输出中,我们可以看出来无论之前的 version 号码是多少,在 reindex 之后...它相当于如下的命令格式:POST _reindex{ "source": { "index": "test" }, "dest": { "index": "test_reindexed...我们可以做如下的练习:我们把 test_reindexed 中的文档的值修改为 Hello Elasticsearch:PUT test_reindexed/_doc/1{ "data": "Hello...", "version_type": "external" }}很显然,由于 test 文档中版本号要低于 test_reindexed 中的版本号,那么我们的文档不会被更新。...在切换之后,在 test_reindexed 中的文档更新过一次。那么在第二次 reindex 的过程中极有可能把 test 中的文档覆盖最新的数据中,从而造成数据的丢失。
