+# Laravel Scout {#laravel-scout}
+After [installing Scout](https://laravel.com/docs/9.x/scout#installation), make sure the models of all tenants aren't being imported in the same index by prefixing the model indices with the current tenant's key. You can achieve that by adding a listener with this code to the TenancyInitialized event in your TenancyServiceProvider:
+
+```php
+config(['scout.prefix' => tenant()->getTenantKey()]);
+```
+
+After that, you can import your existing records for each tenant using the `tenants:run` command:
+
+```
+php artisan tenants:run scout:import --argument="model=App\Models\YourSearchableModel"
+```
