Head shows incorrect docs count if nested type field is defined in mapping

[Xudong You]

I was confused by the docs count value displaying in head plugin if there 
is nest type field define in mapping

For example, I created a new index with following mapping:
{
    "mappings" : {
        "doc" : {
            "properties" : {
                "QueryClicks" : {
                    "type" : "nested",
                    "properties" : {
                        "Count" : {
                            "type" : "long"
                        },
                        "Term" : {
                            "type" : "string"
                        }
                    }
                },
                "Title" : {
                    "type" : "string"
                }
            }
        }
    }
}

And then insert ONE doc:
{
  "QueryClicks":[{"Term":"term1","Count":10},{"Term":"term2","Count":10}],
  "Title":"test title"
}

Then refresh Head, the docs shown on Head is 3:
size: 3.57ki (6.97ki)
docs: 3 (3)

Why?
