[dm-l] CD-Rom electronic editions with full text searching

Hello all, I'm helping a graduate student with a quick survey: does anybody know of CD-ROM editions with full text searching of the entire disk? I've looked through the editions I have, and I'm not sure any of the ones I own have mechanisms for full text searching of all the files on the disk. What she is looking for are texts that produce Google like results, limited solely to the contents of the disk in question, from a text search on CD-ROM. We are of course aware of the new Google beta disk search, and realise that things like HT/dig allow one to do this kind of searching on-line. Thanks in advance for any suggestions. -Dan O'Donnell
