Sean, I haven't looked into this very closely yet, but since you are on the bleeding edge Solr and are looking for pointers, let me point out the new FieldAnalysisRequestHandler and DocumentAnalysisRequestHandler.
[o...@localhost src]$ ff Field\*java | grep Handler.java ./java/org/apache/solr/handler/FieldAnalysisRequestHandler.java [o...@localhost src]$ ff Document\*java | grep Handler.java ./java/org/apache/solr/handler/DocumentAnalysisRequestHandler.java Does that work for you?
