Can you change the name of this event to be past-tense and not so specific to the concept of email. It should be really generic. Look at the `initiated_availability_request` event - that will eventually trigger emails but the search aggregate doesn't know that - it just cares that it publishes to the world that it wants to initiate a request about availability. Same with the method, instead of `send_client_results_email`, It might make sense to rename this to something like `notify_customer_about_results` etc.
