This may be irrelevant, but when only searching a specific format, you can customise your search results; eg: http://www.gnutellaforums.com/limewi...filtering.html

Actually what I was suggesting is the view be changed from the same one, to a variant one that was dependant on the class of material being sought.

Eg. MP3 has metatage for title, artist, albumn etc.
Software, in ziped format, do not
Software, in ISO format, also do not
PDF files have meta tags so title and author can be displayed
DOC files also have meta tags similar to PDF

Video has tags but are not well supported generally like MP3 or PDF. The would change is someone could develop a standard that was extensible, so far that has not emerged.
