This query use phrase prefix and returns 5k records

```auto
POST index/_search
{
  "from": 0,
  "size": 10,
  "query": {
    "match_phrase_prefix": {
      "Identifiers.Identifier.$": {
        "query": "nct"
        "max_expansions": 1024

      }
    }
  }
}

```

When I use following query with wild card it gives me 200K results

```auto
GET index/_search
{
  "from": 0,
  "size": 10,
  "query": {
    "query_string": {
      "fields": [
        "Identifiers.Identifier.$"
      ],
      "query": "nct*",
      "analyze_wildcard": true,
      "boost": 2
    }
  }
}

```

Most of my values in Identifiers has NCT in it , why do I see such a big difference in both these results ?
