Customizing Solr
Solr has the following configuration files:
• <$solr-home>\wblib\conf\schema.xml
• <$solr-home>\wblib\conf\solrconfig.xml
The value for <$solr-home> is the Solr home directory you specified when installing Solr with Windchill.
* 
The default core is wblib. If you plan to use multicore, then this folder would be replaced by the core names.
