Hi, I noticed that my jspwiki search is broken, see below stacktrace. Adding lucene-backward-codecs.jar to the pom.xml, rebuilding and redeploying fixes the problem.
I think it was broken a few versions earlier already, should we add that dependency? cheers, Harry 2020-02-23 14:49:33,077 INFO search.SearchManager - AJAX search failed; java.lang.IllegalArgumentException: Could not load codec 'Lucene80'.
