Hi Roopa, If you look at the diff:
https://github.com/apache/lucene-solr/pull/162/files I didn't change much in SolrIndexSearcher, you can try to skip the file when applying the patch and redo the changes after. Alternatively, the feature branch is available here: https://github.com/bloomberg/lucene-solr/commits/master-solr-8776 you could try to merge with that or cheery-pick my changes. Are you interested in reranking the groups or also in reranking the documents inside each group?

Here are the steps I took on my mac: On branch branch_6_5 Your branch is up-to-date with 'origin/branch_6_5' patch -p1 -i 162.patch --dry-run I am getting Failures for certain Hunks Example: patching file solr/core/src/java/org/apache/solr/search/SolrIndexSearcher.java Hunk #1 FAILED at 1471. Could you please give your input on how to apply this ticket as a patch for branch_6_5 ?
