Hi all

According to the [documentation](https://www.elastic.co/guide/en/elasticsearch/client/java-api/2.4/java-search-scrolling.html), when I set size of N for a scroll, I will get a number of results per page which is equal to N x numberOfShards.

The problem is I can not reproduce this behaviour. In my tests I get the wanted size N and also the order works. Which is fine by me, it's just confusing that the documentation states the opposite.

Did this behaviour changed in version 2.0 (or other version)?

Can I rely on the fact that when using scroll, the size I request is the size I get and also ordered? The Elasticsearch version I'm using is 2.4.

Thank you,  
Valentin

Hi, I'm agree with you, the size N seems not be "per shard". Results are well ordered and scrolled. Strange...
