Hi Joel, I saw your response this morning, and have created an issue, SOLR-8664, and linked it to SOLR-8125. As context, I included my original question and your answer, as a comment.
Cheers Akiel From: Joel Bernstein <joels...@gmail.com> To: solr-user@lucene.apache.org Date: 29/01/2016 13:46 Subject: Re: Exporting Score value from export handler Exporting scores would be a great feature to have. I don't believe it will add too much complexity to export and sort by score. The main consideration has been memory consumption for every large export sets. The export feature powers SQL queries that are unlimited in Solr 6. So adding scores to export would support queries like: select id, title, score from tableX where a = '(a query)' Where currently you can only do this: select id, title, score from tableX where a = '(a query)' limit 1000 Can you create a jira for this and link it to SOLR-8125.
