Re: clustering

Yes, this is definitely the right thing.  Then, you can have full regular
expressions _and_ have it use the index to the fullest extent.  Sounds
perfect -- certainly more powerful than google's stuff.

OTOH, I never use glimpse and just use grep when I'm looking for
something.  And I think I've only once have ever actually needed agrep.
What's more, it's doubtful that I would ever use ifile to classify all my
files and "browse" for what I'm looking for.  In general, search is a much
more powerful strategy.
