Thanks for the pointer Ralph. Just as an aside, I was trying to use the OCLC
CVS repository to check out the SRW/U code...but I wasn't able to figure out
what the project name was. I was able to checkout 'pears' fine like this.
% cvs -d:pserver:[log in to unmask]:/home/CVS/pears/cvsroot
login
% cvs -d:pserver:[log in to unmask]:/home/CVS/pears/cvsroot

All the Lucene code is centralized in
ORG.oclc.os.SRW.SRWLuceneDatabase.java.
It is VERY hard-coded for the DSpace indexes. If you figure out how to get
that information dynamically, I'd love to hear about it.
Let me know if I can do anything to help.
