#Direct integration with a running instance of Solr - http://lucene.apache.org/solr/

#Uses the Solr standard example schema ver 1.1 (no changes made)
# with mappings from the standard Combine XML-profile combine to this
# Solr example schema.

#The conversion is done by the XSLT script in /etc/combine/solr.xsl

#Set Combine configuration variable 'SolrHost' to point to the
# update URL for the running instance of your solr installation
# e.g. if your admin interface is http://mymachine.foo.bar:8180/solr/admin/
# then update is at http://mymachine.foo.bar:8180/solr/update
