Subject Re: New to Solr 5.5
Date Mon, 14 Mar 2016 22:26:10 GMT
OK, take Cassandra out of it for the time being and spend
some time familiarizing yourself with Solr would be my
advice ;)

Yeah, the Solr documentation is a bit scattered, but your most
complete and up to date reference is the Solr reference guide
here:

In particular, see the
https://cwiki.apache.org/confluence/display/solr/Solr+Start+Script+Reference
upconfig command.

You can download the complete reference guide through the link in the
upper left.

The general idea here is that your configurations (solrconfig.xml,
schema.xml and all the rest) are
kept in Zookeeper. When creating a collection, you must reference that
configuration set. The
examples automatically push the configuration set up to Zookeeper,
which you can see in the
adminUI>>cloud>>tree view.

Best,
Erick
