I think the reason behind the "connection reset" is. Looking at the code it points to QueryComponent.mergeIds()
resultIds.put(shardDoc.id.toString(), shardDoc); looks like the doc unique id is returning null. I'm not sure how is it possible as its a required field. Right my unique id is not stored (only indexed) - does it has to be stored for distributed search?
