Thanks, Shawn. I will try to upgrade solr soon Reg firstSearcher: I think it does nothing now. I have configured to use ExternalFileLoader but there the external file has no contents. Most of the queries hitting the collection are expensive and tail queries. What will be your recommendation to warm the first Searcher/new Searcher?
