[ckan-discuss] Problems with Solr searching inside a Dataset ("can not sort on undefined field: metadata_modified")

Tue Aug 20 11:24:26 BST 2013

Hi Javier,

This looks indeed as a problem with the CKAN Solr schema (not the db
one) not being picked up.

What file do you see if you request
http://localhost:8983/solr/admin/file/?file=schema.xml

Is it the CKAN one? It should begin with <schema name="ckan" version="2.0">

Did you restart jettty (sudo service jetty restart) after creating the symlink?

Hope this helps,

Adrià
