I am using Elasticsearch v5.1.1 and getting duplicates back in my results. I thought Completion Suggesters automatically filtered these out.  
Am I doing something wrong?

Query:

```
GET /companies/company/_search
{
  "_source": ["DbaName","company-suggest"],
  "suggest": {
    "company-suggest": {
      "prefix": "grill",
      "completion": {
        "field": "company-suggest"
      }
    }

```

Top 3 results:

```
"suggest": {
    "company-suggest": [
      {
        "text": "grill",
        "offset": 0,
        "length": 5,
        "options": [
          {
            "text": "Grill",
            "_index": "companies",
            "_type": "company",
            "_id": "183221",
            "_score": 1,
            "_source": {
              "DbaName": "Grill",
              "company-suggest": [
                "183221",
                "Grill"
              ]
            }
          },
          {
            "text": "Grill",
            "_index": "companies",
            "_type": "company",
            "_id": "12460",
            "_score": 1,
            "_source": {
              "DbaName": "Grill",
              "company-suggest": [
                "12460",
                "Grill"
              ]
            }
          },
          {
            "text": "Grill",
            "_index": "companies",
            "_type": "company",
            "_id": "297860",
            "_score": 1,
            "_source": {
              "DbaName": "Grill",
              "company-suggest": [
                "297860",
                "Grill"
              ]
            }
          },
```

Hi,  
I confirm, in 2.4.1, the returned results were uniq but in 5.1 all the documents are returned.  
At this time it's a reel problem for us and we'll have to rollback all customers production under 2.4.1 until this bug is corrected or documentations released.

Cheers
