Hi all,
Question about scroll and clear scroll:
Ref: [https://www.elastic.co/guide/en/elasticsearch/reference/2.4/search-request-scroll.html](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/search-request-scroll.html)
The documentation says that
```
The initial search request and each subsequent scroll request returns a new _scroll_id
— only the most recent _scroll_id should be used.
```
and
```
scrolls should be explicitly cleared as soon as the scroll is not being used anymore
```
**My question is**
Does it mean that each loop can clear the previous scrollId, or do we have to call the clear API when everything is scrolled with the list of all scrollIds ?
thx !
Xavier

Hey,
only clear the last scroll id after you are done, dont do that in between, as then your scroll would not work anymore.
