No results - query not returning anything

Hi Adam. I like this demo; thanks for sharing! I got it to work some time ago and am revisiting it. This time, I get 'no results' every time. My elasticsearch is running and when I do a query using head or curl, I get results. How do I troubleshoot? I think the query is not getting to my elasticsearch because I don't see anything in the server stdout in the terminal where es is running. I searched my log for lasagna, and nothing. Please help. Thank you!

Elasticsearch version 1.4.4
