actually, I think the db descriptions are pretty much the same (5GB for testing now, 20GB in the future, so 32GB is a good upper limit), although neither description was very good. however, what is very good is that you told me what it is that I am really looking for: an inverted index. thanks a lot. very helpful. I should be able to search for this now in a much more intelligent fashion.
so I need a nice, fast inverted index program for ubuntu perl. knowing what I need, I could now search cpan. as luck would have it, Search::Moose seems to be designed for this sort of job. (as bad luck would have it, it aborts during the build stage on my ubuntu machine. if someone knows more about Search::Moose, please let me know.)
thanks a lot, everybody.
