Add a way to provide a custom Elasticsearch query

Fix #14842

Are you can see in the following screencast, I was able to define a the following custom query to perform advance operation like fuzziness

{
  "query": {
    "match": {
      "Content.ContentItem.FullText": {
        "query": "{{ term }}",
        "fuzziness": "AUTO",
        "analyzer": "whitespace"
      }
    }
  }
}

Looks good from first quick look.
