   Schema::table('users', function (Blueprint $table) {
       $table->index('email'); // Single-column index

   $posts = Post::with(['comments' => function ($query) {
       $query->where('is_approved', true);
   }])->get();

   foreach ($posts as $post) {
       foreach ($post->comments as $comment) {
           echo $comment->content;
       }
   }
