got a vague impression of what it does]
What I was wondering while I read this: why don't we have a whole
bunch of distributed search engines yet ? Isn't it *weird* that an
activity that lends itself so well for both distributed and parallel
processing is still almost exclusively handled by some handful of
commercial companies ?
Wouldn't searching be much easier if there would be, say, an Apache
indexing module that could dynamically query other known servers in
its environment ? Some search engines seem to work surprisingly well
on huge numbers of pages. What if dozens of people would apply the
same technology on their own servers and have them communicate ?
I know or at least suspect from what I've read that this is basically
part of what Gnutella - or Freenet for that matter - is all about. But
why hasn't this happened before, given the fact that *all* ingredients
seem to have been around for ages: free webserver, search engines that
can be installed locally. All that is missing is a decent protocol (I
understand Gnutella's not great) that efficiently sends both queries
and results around without causing too much traffic. Not that this is
an easy thing to do, but still ...
