we have a large dataset which times out in normal watcher/search and were planning to use "async" search. But after posting such an `async` search, how to then put the output into another index?  
We need the summary information into another index like a summary index for speedier comparison

```auto
POST /sales*/_async_search?size=0
{
  "sort": [
    { "date": { "order": "asc" } }
  ],
  "aggs": {
    "sale_date": {
      "date_histogram": {
        "field": "date",
        "calendar_interval": "1h"
      }
    }
  }
}

```

Why not use a reindex job? [https://www.elastic.co/guide/en/elasticsearch/reference/7.10/docs-reindex.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.10/docs-reindex.html), it can be run async [https://www.elastic.co/guide/en/elasticsearch/reference/7.10/docs-reindex.html#docs-reindex-task-api](https://www.elastic.co/guide/en/elasticsearch/reference/7.10/docs-reindex.html#docs-reindex-task-api)
