//get users ids with where
$user_ids = User::where('first_name', 'like', '%' . $search . '%')->pluck('id');

In User modal you must specify the database connection before above where statement

 protected $connection = 'common_database';

Then where in function to find the practices with user ids

 $practices->whereIn('technician_id', $user_ids);
