I believe you just need to be more specific, or use more words. Not sure what you were searching for to begin with, but "Gun" is too broad and will tell you that it is too short, too common, or something similiar anyway.
So just try to be more specific and that should help.
Yes, the search works very well. I asked for "How to make a poll" the results I got were very helpful. That is how I made the "Shotgun Choke Poll'.......Bob
