I'll warn you in advance that I know nothing at all about the learning to rank functionality. I'm replying about the underlying error you're getting, independent of what your query is trying to accomplish. It's a 404 error, trying to access the URL mentioned above. The error doesn't indicate exactly WHAT wasn't found. It could either be the core named "MODEL1024_1522696624083_shard20_replica_n75" or the "/select" handler on that core. That's something you need to figure out. It could be that the core *does* exist, but for some reason, Solr on that machine was unable to start it. The solr.log file on the Solr instance that returned the error (which seems to be on the machine named vesta, answering to port 9100) may have more detail for the error, or some additional error messages. Normally SolrCloud is good at making sure that requests aren't sent to resources that aren't working. So I'm not sure why this happened. Are there other errors or warnings in the solr.log file, either on the instance where you sent your request, or the instance that returned the 404 error? Thanks, Shawn
