Highlighting is not working in complex query

Elastic Stack Elasticsearch

Hi,
I wanted to use highlight in my query,

My Query is

$query = [
    "filtered" => [
        "query" => [
            "bool" => [
                "should" => [
                    [
                        'query_string' => [
                            'fields' => [
                                'Title.title^4',
                                'Title.ngrams_front^2',
                                'Title.ngrams_back'
                            ],
                            'defaultOperator' => 'or',
                            'query' => $paramsObj->q
                        ]
                    ],
                    [
                        'query_string' => [
                            'auto_generate_phrase_queries' => 0,
                            'enable_position_increments' => false,
                            'fields' => [
                                'Title.title',
                                'Address',
                                'keys'
                            ],
                            'query' => $paramsObj->q,
                            'use_dis_max' => false,
                            'boost' => 2
                        ]
                    ],
                    [
                        'fuzzy' => [
                            'Title.title' => [
                                'value' => $paramsObj->q,
                                'boost' => 1,
                                'min_similarity' => 0.5,
                                'max_expansions' => 20,
                                'prefix_length' => 0
                            ]
                        ]
                    ]
                ]   
            ]
        ],

        "filter" => $filters
    ]	
];

I have tried nested query inside query because i knew highlight will come on same level as query, but still its not working,
can anyone help me stating where the highlight part should go in my query?

The highlighter goes as another "top level" parameter, next to query:

$request = [
  'query' => [
    'filtered' => [
      ...
    ]
  ],
  'highlight' => [
      'fields' => [
        'my_higlighted_field' => (object) []
    ]
  ]
];
