@mattyb149 Ok. Changes are made. I refactored the commit to be based on a
controller service. For now, that service only handles a single function: basic
search. However, there is now a (hopefully) extensible base via a controller
service to move forward. The controller service has integration tests only; the
processor has junit tests with a mock service.---
