Hi All:  
I have been using elastics4s module for searching and I have been using  
it with some amount of success. Its not been all successful because, I have  
one scenario where the API seems to fail.

case in point. :

search in "index/type" limit 100 query {  
ids(docIds)  
} scroll ("5m")

Case that works : - I am able to scroll through the results and get all of  
the documents.

client:ElasticClient = ElasticClient.remote(setttings, ("host1",9200))

Case that does not work : - I get only the first page of results and  
scrolling does not work.

client:ElasticClient =  
ElasticClient.remote(settings,("host1",9200),("host2",9200))

My Question about scrolling is does it work only when one node is used in  
the configuration or does it work when multiple nodes are specified in the  
configuration.

Thanks

Ramdev

Interesting question. I can't find anything in the scroll docs that says it  
would be single node only, so I guess the next question is - does this work  
in the Java client for you? If so, raise a bug issue on  
[GitHub - sksamuel/elastic4s: Elasticsearch Scala Client - Reactive, Non Blocking, Type Safe, HTTP Client](http://github.com/sksamuel/elastic4s) if you can.
