Question

我正在使用批量请求执行弹性搜索全索引。在索引编制过程中出现问题，结果显示为空。当我在完整索引期间删除索引时，如何处理这种情况。

我已经完成了以下步骤：

删除索引
创建索引
创建映射
批量请求

索引属性和映射：

如果希望完整索引在重新索引期间可用，则唯一的选择是在完成索引编制后才删除原始索引。在这种情况下，我可能会使用aliases。例如，假设products-2020.07.28是当前索引，那么您将为今天创建一个新索引，并在完成索引后立即更改别名。

创建索引

PUT /products-2020.07.28
{
  "settings": {
    ... your settings ...
  },
  "mappings": {
    ... your mappings ...
  }
}

批量索引请求

将别名更改为新索引

POST /_aliases
{
  "actions" : [
    { "remove" : { "index" : "products-2020.07.27", "alias" : "products" } },
    { "add" : { "index" : "products-2020.07.28", "alias" : "products" } }
  ]
}

删除旧索引
```
DELETE /products-2020.07.27
```

然后，任何请求都可以直接转到别名，而不是索引。

GET /products/_search

这样，您无需用户注意即可重新编制索引。
