Erick, I would like to add that the interesting behavior i.e point #2 that I mentioned in my earlier reply happens in all the shards , if this were to be a distributed search issue this should have not manifested itself in the shard that contains the key that I am searching for , looks like the search is just failing as whole intermittently .
Also ,the collection is being actively indexed as I query this, could that be an issue too ? Thanks.
