Answer 1

You need to set require_field_match value to false as by default, only fields that contains a query match are highlighted.

{
  "query": {
    "match": {
      "file": "hello"
    }
  },
  "highlight": {
    "require_field_match": "false",
    "fields": {
      "title": {},
      "email": {}
    }
  }
}
