Livewire Computedの使い所は検索機能
====

```php
namespace App\Livewire;

use App\Models\Post;
use Illuminate\Contracts\Pagination\Paginator;
use Illuminate\Database\Eloquent\Builder;
use Livewire\Attributes\Computed;
use Livewire\Component;
use Livewire\WithPagination;

class Posts extends Component
{
    use WithPagination;

    public string $search = '';

    #[Computed]
    public function posts(): Paginator
    {
        return Post::query()
                    ->whereAny(['title', 'content'], 'like', "%$this->search%")
                    ->latest()
                    ->paginate();
    }

    // render()は省略可。
}
```
inputへの入力に応じて検索結果がリアルタイムに更新される。
```php
<input type="text" wire:model.live="search">

@foreach($this->posts as $post)

@endforeach
```
