Default Solr Home Directory
=============================

This directory is the default Solr home directory which holds
configuration files and Solr indexes (called cores).


Basic Directory Structure
-------------------------

The Solr Home directory typically contains the following...

* solr.xml *

This is the primary configuration file Solr looks for when starting;
it specifies high-level configuration options that apply to all
of your Solr cores, such as cluster-wide SolrCloud settings like
the ZooKeeper client timeout.

In addition, you can also declare Solr cores in this file, however
it is recommended to just use automatic core discovery instead of
listing cores in solr.xml.

If no solr.xml file is found, then Solr assumes that there should be
a single SolrCore named "collection1" and that the "Instance Directory"
for collection1 should be the same as the Solr Home Directory.

For more information about solr.xml, please see:
https://cwiki.apache.org/confluence/display/solr/Solr+Cores+and+solr.xml

* Individual SolrCore Instance Directories *

Although solr.xml can be configured to look for SolrCore Instance Directories
in any path, simple sub-directories of the Solr Home Dir using relative paths
are common for many installations.

* Core Discovery *

During startup, Solr will scan sub-directories of Solr home looking for
a specific file named core.properties. If core.properties is found in a
sub-directory (at any depth), Solr will initialize a core using the properties
defined in core.properties. For an example of core.properties, please see:

example/solr/collection1/core.properties

For more information about core discovery, please see:
https://cwiki.apache.org/confluence/display/solr/Moving+to+the+New+solr.xml+Format

* A Shared 'lib' Directory *

Although solr.xml can be configured with an optional "sharedLib" attribute
that can point to any path, it is common to use a "./lib" sub-directory of the
Solr Home Directory.

* ZooKeeper Files *

When using SolrCloud using the embedded ZooKeeper option for Solr, it is
common to have a "zoo.cfg" file and "zoo_data" directories in the Solr Home
Directory. Please see the SolrCloud wiki page for more details...
