`doc_count` is incremented when adding the same document several times.

To reproduce execute twice:

> ```
> PUT /test_index/_doc/1
> {
> "somefield": "somedata"
> }
> 
> ```

There is 1 document in the index but doc\_count=2:

> ```
> {
> "_index" : "test_index",
> "_type" : "_doc",
> "_id" : "1",
> "_version" : 2,
> "found" : true,
> "took" : 0,
> "term_vectors" : {
> "somefield" : {
> "field_statistics" : {
> "sum_doc_freq" : 2,
> "doc_count" : 2,
> "sum_ttf" : 2
> },
> "terms" : {
> "somedata" : {
> "term_freq" : 1,
> "tokens" : [
> {
> "position" : 0,
> "start_offset" : 0,
> "end_offset" : 8
> }
> ]
> }
> }
> }
> }
> }
>

Is that expected?  
If for instance I compute TFIDF on terms for a document inserted several times (whatever the reason), this will be wrong.
