How to Use Haystack in Phoenix

Alan: Haystack is something I'm thinking about these days, having some tech searching in there and stuff for products. It's nice not to have another service, right? Just everything within memory. So yeah, it ends up being super simple. And you basically provide a module with a few configuration things. You can either so like because the state of the Haystack lives inside the application, when you deploy, you're obviously going to lose that state. But then I wanted this to be basically you as someone who wants to implement Haystack should be able to choose where it's hydrated back.
