Different times of the day and night show different results as well..
I was trying to find a part 2 to a movie I wanted I knew it was there because I had seen it the night before, search after search I kept getting nothing, so I typed in the titile right down to the xvid dvdsr cd2 done1, and there it was with 12 hosts, whereas the night before I didnt have to go into such detail just the name, to recieve the results....
Sometimes it pays to spell things in a different way as well ie: mullens, mullans, mullins....
This will show different results as well, but all being the same artist just spelt different ways...It pays to play around with your searches....
Happy downloading ....
