Looking for web indexer in python

[Roy Smith]

The software development group I work in has a small internal web site (a 
few hundred documents) which we don't currently have any way of searching.  
I'd like to put an automated indexer/search system in place.  If possible, 
I'd like to use python, since I think it would be a nifty way to introduce 
the group to the language.  There's no funding for this, so it has to be 
free software.

A cursory look around didn't turn up anything that would fit the bill, but 
I have to assume somebody's already done a free python web indexer.  Any 
suggestions?
