: What should I be doing to fix them? Is there a replacement for those : classes? Do I just need to change the luceneMatchVersion to be LUCENE_461 : or something?
that's pretty much exactly what that warning message is trying to tell you -- your config ways to use LUCENE_33 mode, but that won't work once 5.0 comes out. so at some point you need to increase that to at least LUCENE_40 and re-index to make the warning go away (and to be able to upgrade to Solr 5.0) If you have suggestions for how to improve the warning message please let us know. -Hoss http://www.lucidworks.com/
