Hi,

We have around billions of documents in elastic search, we would like to do bulk retrieval from elastic using Java HTTP client. Can someone recommend best approach of doing this. It would be really helpful if any sample is available.

Thanks

Hi,

If you want to retrieve all your documents, you have to run a query **match\_all()** ([https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-query-dsl-match-all-query.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-query-dsl-match-all-query.html)) using a scroll ([https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-search-scrolling.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-search-scrolling.html)).

bye,  
Xavier
