## 配置模型索引

每个模型与给定的搜索「索引」同步，这个「索引」包含该模型的所有可搜索记录。换句话说，你可以把每一个「索引」设想为一张 MySQL
数据表。默认情况下，每个模型都会被持久化到与模型的「表」名（通常是模型名称的复数形式）相匹配的索引。你也可以通过覆盖模型上的 searchableAs 方法来自定义模型的索引：

declare (strict_types = 1);
namespace app\model;
use think\Model;
use tp5er\think\scout\Searchable;

/**
 * @mixin \think\Model
 */
class User extends Model
{
    use Searchable;
    
    /**
     * Get the index name for the model.
     *
     * @return string
     */
    public function searchableAs()
    {
        return $this->getTable();
    }

declare (strict_types = 1);
namespace app\model;
use think\Model;
use tp5er\think\scout\Searchable;

/**
 * @mixin \think\Model
 */
class User extends Model
{
    use Searchable;
    
    /**
     * Determine if the model should be searchable.
     *
     * @return bool
     */
    public function shouldBeSearchable()
    {
        return true;
    }
