Elastic Stack Elasticsearch

Questions related to elasticsearch search.
In an instance using 4Gb memory,
elasticsearch dies with OOM when querying data over 4Gb with scroll API, What about search_arter ??

Would not it be okay to search 50Gb for search_arter?
If i want to output all data to a file, it can be over 50Gb.
I can not predict the internal behavior.
Do you know anyone?

I simply used the java high level API to search all the documents.
(match_all)

for () {
search (scroll_id);
scroll_id = get scroll_id ();
}
