2. There were a buncha files in solr_home/lib that were about solr "cell", the content extraction plugin. We don't use this. Rather than try to figure out how to upgrade it, I just removed those files.
What remains is:
* apache-solr-umichnormalizers.jar
* normalizer.jar
* UnicodeNormalizeFilter.jar
I'm not sure why we need three jars for this, but trying to remove any seemed to disturb functionality, so just leaving this there for now. Also, the "apache-solr-umich" one, I think, is from
Bob@umich, NOT from the solr project, so probably shouldn't begin with "apache-solr-", but leaving it alone for now. Not entirely sure what the others are, but removing any of them seems to cause problems.
Restarted tomcat. Seems to be working fine.
