[xwiki-devs] Fw: [ANNOUNCE] Apache Solr 5.0.0 and Reference Guide for Solr 5.0 released
FYI. Could be interesting for us to upgrade. Don’t know if it’s backward compatible with 4.x or not though.

It is, but not with 3.x. The lucene module has been removed from XE, so that doesn't matter, but I can't remember if we ever used Solr 3.x?
