How to do web-scraping of contents in TripAdvisor using YQL

I am quite new to web scraping so my question might be a little simple but it really bothers me a lot. I want to scrap some contents from TripAdvisor, but when I run the following command in YQL, it returns nothing.

select * from html where url="http://ift.tt/1RbuElV"

Can anyone tells me why? Is there anything wrong with my commands?

Thank you in advance for your kind help.
