```auto
curl -X PUT "localhost:9200/test_index?pretty" -H 'Content-Type: application/json' -d'
{
  "mappings": {
    "properties": {
      "search_as_you_type_field": {
        "type": "search_as_you_type"
      }
    }
  }
}
'

curl -X PUT "localhost:9200/test_index/_doc/1?refresh&pretty" -H 'Content-Type: application/json' -d'
{
  "search_as_you_type_field": ["owl", "quick brown fox dog"],
}
'

curl -X PUT "localhost:9200/test_index/_doc/2?refresh&pretty" -H 'Content-Type: application/json' -d'
{
  "search_as_you_type_field": ["quick brown fox dog", "owl"]
}
'

curl -X GET "localhost:9200/test_index/_search?pretty" -H 'Content-Type: application/json' -d'
{
  "query": {
    "match_phrase_prefix": {
      "search_as_you_type_field": {"query": "quick brown fox d"}
    }
  }
}
'
this returns the second document but not the first

```

`match_phrase_prefix` query on a search\_as\_you\_type field doesn't seem to work properly as expected. In the example above first document is indexed with ["owl", "quick brown fox dog"],  
querying `q, qu, qui, .. quick b.. , quick brown f..` works but `quick brown fox d, quick brown fox do, quick brown fox dog` doesn't. However all the possible prefix queries works for the document 1.

I'm not sure this is an expected behavior but seems pretty strange and it is not documented anywhere
