My final year University project was to create an Open Source mailing list
archive :) I did quite a bit of reading into information retrieval and
assorted algorithms and data structures. I had a prototype running for
quite some time, but is currently down as I am wiping the machine to start
again in python :) The original system was a mix of C/Perl/Python and
returned results in XML which then were formatted via XSLT.
Once I get a spare minute I am going to try and re-implement it in Python
and using ZODB (with BerkeleyDB storage) I might try and port some of the
code over to work as a PluggableIndex too.
One of the main tasks is to write a python wrapper around my compression
code. I will have to look more closely at how to write Python modules in
C, as it does lots of bit twiddling which is in a very tight loop. The
object will basically be a compressed list to which you can append
ascending integers and will allow various fast union/intersection
operations with other similar objects. This in itself may be sufficent to
use in a PlugginIndex.

Unfortunately I don't have the time. Unless I can use it myself directly
in a project we have funding for (or unless anyone wants to fund my time
to develop it) I will have to wait until I have some more time on my
