Hello I want to display the first_name, last_name, subject from the tables using models in laravel after the search but whenever I try to find subject_name using the models I get error below
Exception
Property [subjects] does not exist on this collection instance.
My search functionality is working fine I am just having a problem with displaying the results i.e. first_name, last_name, subject.
I tried to fetch the results from the search keywords and it returned the array of the search matched now I want to display its specific columns that I mentioned above.
User Model

use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
use Notifiable;

->orWhere("keyword_title5",'LIKE', '%' . $search . '%')->get();
if(count($find)>0) {
echo $find;
dd($find->subjects->subject_name);
// echo $find->user->first_name;
die();
return view('review.showReviewPage', compact('find', 'search'));
} else {
Session::flash('message', 'No keyword matched');
return redirect('/home');
}
