   1. Find the lucene jar file that your version of solr is using. You can do this by copying
your solr.war file somewhere and unpacking it (jar xvf solr.war). Your lucene jar file should
be in WEB-INF/lib. It is probably called something like lucene-core-2007-05-20_00-04-53.jar.
Copy it somewhere easy to find.

Copy this new directory to the location of your application's solr index (move the old one
aside first, of course) and start solr.
