Well, I would initially say that it was becuase of whatever you were searching, try searching anything popular and hope for results. Otherwise, I would say that you might have a firewall problem, but you did say that you got one result, so in that case, I might say that it has to do with the hosts you have.
Go to, View > Show/Hide > Connections, and look at the hosts there. Well, that's all I can say about your problem, I'm kinda new too, so I don't know enough to get into the nitty gritty details. if you post again with some more info I may be able to help more.
