What is the proper path for solar in the pantheon.settings.php file?? $conf['apachesolr_path'] = '\default';is NOT WORKING IN 1.2

These were originally configured as:
$conf['apachesolr_port'] = '8983';
$conf['apachesolr_path'] = '/pantheon_dev'; # or /pantheon_test or /pantheon_live

If you are trying to setup additional sites, or are changing the default configurations:

• We configure solr to run on port 8983.
• The path variable should be prefixed by a forward-slash (/).
• The path variable refers to /etc/tomcat6/Catalina/localhost/pantheon_dev.xml (for example). So for a path of /default you would need to have a default.xml file.
• In the default.xml file, the solr/home attribute needs to point to a valid solr home directory (The pre-configured folders are in /var/solr/pantheon). A 'blank' copy of this folder can be found in /opt/pantheon/fab/templates/solr.
