我正在尝试将所有文​​档都添加到索引中，我尝试了以下操作-

1）首先获取记录总数，然后设置/ _search？size =参数-无效，因为size参数限制为10000

2）尝试通过多次调用进行分页，并使用了参数'？size = 1000＆from = 9000' -直到'from'为

"Result window is too large,from + size must be less than or equal to: [10000] but was [100000]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level setting"

那我该如何检索索引中的所有文档？我读了一些建议使用滚动api甚至文档状态的答案-

"While a search request returns a single “page” of results,the scroll API can be used to retrieve large numbers of results (or even all results) from a single search request,in much the same way as you would use a cursor on a traditional database."

但是我找不到任何示例查询来在单个请求中获取所有记录。

索引中总共有388794个文档。 另外请注意，这是一次通话，因此我不必担心性能问题。
