Hey HacktheUniverse team -- very cool project!
I am getting an interesting response when attempting to use the search endpoint. The documentation, for example, is returning:
$ curl http://star-api.herokuapp.com/api/v1/search?q=%22Sun%22
{"status":"500","error":"Internal Server Error"}

On the other hand, when I try a different search, like the star "HIP1 HD224700 Gli", a null response comes back:
$ curl http://star-api.herokuapp.com/api/v1/stars/search?q=%22HIP1%20HD224700%20Gli%22
null

Am I incorrectly forming the URL?
