WithoutTenantId not working properly on method level

I have Book objects with different tenantIds. But I want to retrive all tenantsId objects from the domain object. But it is not retrieving. It is showing empty list.My method is below.WithoutTenantId not working

For example my book documents are:

| id | bookName | tenant_id |
| --- | --- | --- |
| 1 | abc | 2 |
| 2 | xyz | 3 |

I want to pull both tenant 2 and 3 data.

```
@WithoutTenant
List findAllBooks(){
List bookList=Book.findAll()
return bookList;

}
```
