Hi Shawn, Definitely helpful to know about the instance and files stuff in Admin. I'm not running cloud, so I looked in the /conf directory but there's no schema.xml:
Here's what's in my core's Files: currency.xml elevate.xml lang params.json protwords.txt solrconfig.xml stopwords.txt synonyms.txt and echoed by ls -l: -rw-r--r-- 1 root root 3974 Feb 15 11:38 currency.xml -rw-r--r-- 1 root root 1348 Feb 15 11:38 elevate.xml drwxr-xr-x 2 root root 4096 Mar 23 10:46 lang -rw-r--r-- 1 root root 29733 Mar 23 18:04 managed-schema -rw-r--r-- 1 root root 308 Feb 15 11:38 params.json -rw-r--r-- 1 root root 873 Feb 15 11:38 protwords.txt -rw-r--r-- 1 root root 60591 Feb 15 11:38 solrconfig.xml -rw-r--r-- 1 root root 781 Feb 15 11:38 stopwords.txt -rw-r--r-- 1 root root 1119 Feb 15 11:38 synonyms.txt -----Original Message----- From: Shawn Heisey [mailto:apa...@elyograg.org] Sent: Thursday, March 26, 2015 7:28 PM To: solr-user@lucene.apache.org Subject: Re: i'm a newb: questions about schema.xml On 3/26/2015 4:57 PM, Mark Bramer wrote: > I'm a Solr newb.

Hopefully you know what core you are using, so you can go to the admin UI and find it in the "Core Selector" dropdown list. Assuming you can do that, you will find yourself looking at the "Overview" tab for that core. https://cwiki.apache.org/confluence/display/solr/Using+the+Solr+Administration+User+Interface Once you are looking at the core overview, in the upper right corner of your browser window is a section called "Instance" ... which has an entry that is ALSO called "Instance." Inside the directory indicated by that field, you should have a conf directory. The config and schema for that index are found in that conf directory. If you're running SolrCloud, then you can forget everything I just said ... the active configs will be found within the zookeeper database, and you can use the Cloud->Tree tab in the admin UI to find your collections and see which configName is linked to each one. You'll want to become familiar with the zkcli script in server/scripts/cloud-scripts. https://cwiki.apache.org/confluence/display/solr/Command+Line+Utilities Whether it is SolrCloud or not, you can always LOOK at your configs right in the admin UI -- click on the "Files" tab after you select the core from the selector. Thanks, Shawn
