Hi,
I just checked, but I’m getting results from that site, for example: https://i.imgur.com/0LlkHw7.png
I believe the problem here is rather that you have a very large data set and the default keyword logic is aiming to return as many results as possible. I would highly suggest changing your keyword logic to “AND with exact keyword matches” on the General Options -> Behavior panel. It will reduce the results count greatly, but return much more relevant ones: http://i.imgur.com/l72YTWX.png
