Phrase Suggester return whole field

Elastic Stack Elasticsearch

Hi, I'm trying out the Phrase Suggester and wondering if there is a way to make it always return whole fields? For example, when I search noble I want the suggestion to be nobel prize rather than just the term nobel.

My search query looks like this:

{
    "query": {
        "match": {
            "title": "this"
        }
    },
    "suggest": {
        "text": "that",
        "simple_phrase": {
            "phrase": {
                "field": "title.trigram",
                "size": 1,
                "gram_size": 3,
                "direct_generator": [
                    {
                        "field": "title.trigram",
                        "suggest_mode": "always"
                    }
                ],
                "highlight": {
                    "pre_tag": "<em>",
                    "post_tag": "</em>"
                }
            }
        }
    }
}

And the index is set up like this:

    "settings": {
      "index": {
        "number_of_shards": 1,
        "analysis": {
          "analyzer": {
            "trigram": {
              "type": "custom",
              "tokenizer": "standard",
              "filter": ["lowercase","shingle"]
            }
          },
          "filter": {
            "shingle": {
              "type": "shingle",
              "min_shingle_size": 2,
              "max_shingle_size": 3
            }
          }
        }
      }
    },
    "mappings": {
      "properties": {
        "title": {
          "type": "text",
          "fields": {
            "trigram": {
              "type": "text",
              "analyzer": "trigram"
            }
          }
        }
      }
    }
  }

I'd really appreciate any suggestions here! Thanks
