Best way to load a ton of JSON data into an Ember App

Added term.term and it still brings back an array of 29. Added this.get("/terms/:letter") to mirage and it does the same. I’m thinking needs to be a mirage solution. But I’ve tried various adapters and serializers, along with refactoring your search code and not getting anywhere. Sometimes I wonder if I should create a separate letter model but that seems like overkill.
