Search with LIKE expression in nested object with Moloquent

Question

I'm trying to implement filter for logs in the Laravel5 model. Logs stored in mongodb collection.

The record has this structure. But this structure is not fixed! It can be just an object with not all of these properties. Moreover it can be very different

So here is one possible:

{
   "_id": ObjectId("5950cacd64b6bd1324005095"),
   "request": "44b2fd871f989bb5a1416cbee2dbae5f",
   "type": "calculate",
   "data": {
     "request": {
       "request_uri": "http://api.server/method/packet/260c013a7b791b93997dd7b9abf15f68/go",
       "region_id": "249",
       "country_id": "",
       "count_insureds": "1",
       "citizenship_id": "198",
       "period": "18",
       "date_from": "2017-06-30",
       "date_till": "2017-07-17",
       "last_name": "Asdasd",
       "first_name": "Sasd",
       "birthday": "1978-06-08",
       "passport": "WE211",
       "email": "",
       "address": "",
       "identific": "",
       "persons": {
         "1": {
           "last_name": "",
           "first_name": "",
           "birthday": "",
           "passport": "",
        } 
      },
       "igree_1": "1",
       "igree_2": "1",
       "gateway": "mygateway",
       "packet_id": "99",
       "_token": "5288e7875e97d165443fba0e6b5577ff" 
    },
     "response": {
       "hash": "44Qwf5T6znXx2",
       "sn": "КМ5000073",
       "total_price": "899.87000000",
       "total_price_formatted": "899.87",
       "currency": "EUR",
       "total_base_price": 14.58,
       "rate": "29.0445" 
    } 
  },
   "updated_at": ISODate("2017-06-26T08:50:21.0Z"),
   "created_at": ISODate("2017-06-26T08:50:21.0Z") 
} 

And here is another one:

{
   "_id": ObjectId("5950cac964b6bd1324005093"),
   "request": "094932d4f83069b9e0ac759277a557b0",
   "type": "draft",
   "data": {
     "BILL_AMOUNT": "899.87",
     "SHOPORDERNUMBER": "357397a1fdf22a4daac6c955e1bd71-S9F8wGTjBRzGAVYw-1498466995",
     "APPROVALCODE": "TESTPM",
     "RECEIPT_URL": "https://www.website.com/services/receipts/get-receipts/shop-bill-id/35343744448e8c7f62e266e9ddb9345785357cf7b526bdca57e971720a7dfff4c5850f2e24a [...]",
     "TOKEN": "18323839313034333331160415C2A559EBAF18E61D2739BBEF7AB5681A10B15A7CB29E6ACC12EACAC46C0C0F297EEC04918B4811E223656B776214E5B2EC5818E7394698D5BF07FB17699E [...]",
     "CARD_PAYMENT_SYSTEM": "VISA",
     "CARD_LAST_DIGITS": "1111",
     "RESULT": "0" 
  },
   "updated_at": ISODate("2017-06-26T08:50:17.947Z"),
   "created_at": ISODate("2017-06-26T08:50:17.947Z") 
} 

I've wrote scope-method for filtering data. It looks like this:

public function scopeFilter($query, $filters)
{
    if ($requestType = array_get($filters, 'request_type')) {
        $query->where('type', '=', $requestType);
    }

    if ($data = array_get($filters, 'data')) {
        //$query->where('data', 'like', '%' . trim($data) . '%');
        $query->raw(function ($collection) use ($data) {
            return $collection->find([
                'data' => [
                    '$in' => [$data]
                ]
            ]);
        });
    }
    // ...
}

The problem is: I can't filter data because it has different structure. As you can see I've tried to search with LIKE statement but it is useless. And filtering with $in return me all records.

Any suggestion will be appreciated.

Thanks in advance.
