[jira] [Commented] (SOLR-1632) Distributed IDF
[ https://issues.apache.org/jira/browse/SOLR-1632?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13142603#comment-13142603 ]
Mark Miller commented on SOLR-1632:
-----------------------------------
Recently I updated this patch to trunk and got rid of the threadlocal usage and Query rewriting that was the reason we had to pull this from trunk long ago - then I attempted to override stats on IndexSearcher with global stats - this is when I realized that had no affect on scoring anymore - this will now be addressed LUCENE-3555. Unfortunately, I didn't pay attention and lost that code. It's unfortunate, because it would have been a nice head start on this issue - I think we may want to make other changes/improvements, but would have been a start with something working. It was a half pain to do since the patch has to be manually applied, but perhaps doing it a second time is faster...
