I would really like to refine the search results... that is a search within the search results or better yet a filter that could be applied to search results allowing various patterns to be searched while retaining the original search results.

There are occasions where I am looking for a given song by a given artist... I have found that typos and outright misspelling cause results to be erratic... so if I know the song is by say, Jackson Browne, I do a 'net' search for Jackson Browne and the would be able to search/filter the results for the song or fragment of song.
