In a Gnut shell

I have tried to use this program sveral times. And I have to say I'm not impressed. If I type in a search for the most obvious thing I can think of, say Elvis I wait for over 15 mins and still nothing is found. So I try looking for mp3 and after 15 mins still nothing. So I'' go back to elvis again and all of a sudden I'll get 200 results. Now its good that I eventually get results but having to wait for 30 mins is not good. Sure its better than nothing but its incredibly fustraiting. I'm just wondering why so many people have no problem and others can't get the bloody thing to work!!!
