To make request like your requirement, just set form with this content, example in resources\views\home.blade.php:

<form method="get" enctype="multipart/form-data" action="{{ route('search.data') }}">
  <select class="form-control" name="filter[dbfieldname1]">
      <option class="hidden" disabled selected>Admin List </option>
      <option value="1">Value 1</option>
      <option value="2">Value 2</option>
  </select>
  <select class="form-control" name="filter[dbfieldname2]">
      <option class="hidden" disabled selected>Agent List </option>
      <option value="1">Value 1</option>
      <option value="2">Value 2</option>
  </select>
  @csrf
  <input type="submit" value="Search Data" />
</form>

Configure the route routes\web.php:

Route::get('/search/data', [App\Http\Controllers\HomeController::class, 'search'])->name('search.data');

Then set search function as app\Http\Controllers\HomeController.php:

// Get search data
public function search(Request $request)
{
    logger('Function search is working.');
    $filter = $request->filter;
    if($filter) {
        if(isset($filter['dbfieldname1'])){
            logger('Value of dbfieldname1:');
            logger($filter['dbfieldname1']);
        } else {
            logger('Admin list is not choosen.');
        }
        if(isset($filter['dbfieldname2'])){
            logger('Value of dbfieldname2:');
            logger($filter['dbfieldname2']);
        } else {
            logger('Agent list is not choosen.');
        }
    } else {
        logger('Not any lists choosen!');
    }
}

Clear storage\logs\laravel.log, then you will get successful result!

[2022-03-05 05:53:54] local.DEBUG: Admin list is not choosen.
