When changing SOLR’s schema, it is not enough to just change the file itself. Solr does not dynamically load the file. As long as no action is taken, the old schema will still be in effect.
After updating the schema.xml you can either:
- Restart SOLR or Tomcat (depending on your configuration)
- Reload the core that will use the new schema
Relaoding the core can be done using the reload action:
http://localhost:8983/solr/admin/cores?action=RELOAD&core=core0
Where core0 is the core you want to restart. You can visit the cores page to make sure the core is successfully restarted.
