you can type hine request object inside each query filter construct since laravel will make instance from the container

thanks Alex, may I ask if we can implement a specific interface for these pipleline query builder classes ? so that they all follow the same instructions ( implement same methods ) ?

My second question is about if there is a way to automatically add these classes to the pipeline without modifying the code in the controller.

Nice effort from such a great tutor
