Limit filter based on role

[akulmehta]

I have a situation where I am allowing filters based on IDs like:

    $posts = QueryBuilder::for(Post::class)
        ->allowedFilters([
            AllowedFilter::exact('id'),
            AllowedFilter::partial('title')
        ]);

For users with role editor, I want to be able to show all the posts so no filter is required.

For user with role of viewer, I want to hide the private posts, unless they are explicitly allowed to peek at the post or they are the creator of the post.

So for this I have implemented something like this,

   // If the user is of level viewer i.e. role_id > 3
   if ($user->role_id > 3) {
      // allow to view public visibility
      $posts= $posts->where('visibility', '=', 'public');

      //allow to view if peeking is granted
      $posts =  $posts->orWhereHas('peek', function ($query) use ($user, $params) {
        $query->where('user_id', $user->id);
      });
      
      //allow to view if creator
      $posts = $posts->orWhereHas('creator', function ($query) use ($user, $params) {
        $query->where('user_id', $user->id);
      });

The issue is that when we try to filter the posts by title it still gets all the posts where the user has peeking rights. So how can the filter be applied to this?
