I received one as well. Most of the time it sits on mute, to be honest. (It sits right next to the TV and sometimes the TV would cue it into action and it would respond to what it thought was a legitimate query)

I found that for some music, it would find a radio station named after exactly what I was looking for (for instance a 'station' that only plays the one band or one song) after prompting me to get Google Play.

The most used function on there is the built-in trivia app my girlfriend and I play Saturday mornings while we're doing other things.

I never had a real problem with the search function, though. I'm surprised it wouldn't find results for that question. Did you have location disabled?
