Upgrade to the latest Lucene version

Hi all, I was wondering if anyone is planning to (or is already) working on upgrading the main branch of Solr to the latest Lucene version. I’m about to start contributing a new feature (Add support for PatienceKnnVectorQuery ), which was introduc

Re: Proposal to improve vulnerability and VEX presentation

Hi Piotr, I've a few questions below, but don't read any of those as casting doubt on the overall idea. By and large, this all sounds great! I'd be happy to review them if you're still willing to implement. Questions: 1. You mention towards the end of your email the idea of migrating the VEX e

Re: Clarification on Issue #754 in Solr Operator – Fix Timeline and JIRA Requirement

Hi Kamal, Solr (which includes the operator) is a volunteer community. So we don't really offer timeline estimates around fixes, because there's no way to predict if or when a volunteer might happen to pick up the ticket. To your other question: opening an "Issue" on Github is sufficient for ope

Re: [EXTERNAL] - Planning and Releasing Solr 10.0

Hi Isabelle, Apologies for the late reply on this. The Jetty 12 upgrade has been merged, but unfortunately there's still at least one blocker for the Solr 10 release that folks are working through (https://issues.apache.org/jira/browse/SOLR-17631). That means it's pretty unlikely that work on a

Re: Remaining work for Lucene 10

Grouping behaviour has changed in Lucene in terms of how the order of groups are returned. We either need to work around that to provide backward compatibility or support the new behaviour. Christine has done some investigation around it and I have been looking at it, on and off, for a few months n
