How to implement a search box in an Ember app

I recently began with the Ember framework and have an app running fine and using ember-cli (v 0.2), ember-data and powered by a Rails app.

I would like to implement search functionality in the app where I get to type in an input field and the search results are displayed in a dropdown list (much like the one in the Discourse app itself). How do I approach the same?

Btw, I have an api powered by a Rails app using Grape and MongoDB.
