I setup a cluster with two nodes(2 shards+1 replica) without save the  
\_source.  
Through the ES head, the cluster is green, and I see the docs is about 0.9  
billion;  
but after some time without doing any thing, the docs becomes to 0.45  
billion or so.  
More strange, after some time again without doing any thing, the docs  
becomes to 0.9 billion again.  
Who can help explain how ES calculate the docs numbers??
